Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Sep 11 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

A very fun spiritual successor to the dead and buried pvz franchise. The development may be a bit slow but remember that a single dev (maybe more now) is handling this game.
This game has been a great experience, and while there are only 3 worlds finished, it still provided a solid amount of playtime. Each enemy and tool for the player was more than an answer for a single scenario and had an application that was deep and intuitive while complementing the fast-paced gameplay, and the way the game never forced a single strategy on me to counter a threat is really appreciated. When it comes to improvements, the only ones I can suggest are nitpicks like the almanac of the game not organizing the elixirs very well (what I mean is that it would be nice if there were icons for turrets that lack an upgrade of a certain type or when the player hasn't used it in a level for the sake of filling the almanac) and a way of looking at the present enemies of a current level without the need of entering said level for the sake of replay value; but these little nitpicks are only that little, and the game is not ruined if these are not changed, and that is good because the game is good and a must-play for any person that finds fun with tower defense games also the ost is very good and art looks really nice.

This is my new favorite tower defense game. Pros: Enemies attacking turrets - Turrets being attacked will create situations where you will have to make strategic sacrifices and have to plan turret positioning in response to the enemies attacking, not just the most optimal spot for damage like in Bloons Tower Defense Controllable character - Playing as a character instead of being "outside the game" is great because you have to plan your pathing so you don't get attacked by the enemies, creating more strategic depth Limited turret buying power based on the level - Don't have to place down a million sunflowers again and again like in PvZ The same upgrades that can be used on any turret - Potion upgrades allow for so much variety, in many games there would be a turret for slowing or a turret based off another turret that has more benefits, but with this you can use any combination of ice, invincible, or more bullets / reloading for easy to make, in depth strategies Great enemies and turrets Great difficulty Cons: There should be clouds in the sky that even seals can't shoot through so you have to strategize how to deal with enemies around walls without placing down seals whenever convienent or something like the equivalent of the cloud There should be a grim reaper to turret death equivalent of sushi conveyor - Sushi conveyor allows for the player to have to improvise and come up with new plans, but I hate RNG so much, I think there should be an enemy like the grim reaper that can't be killed and that gives you turret choice debuffs so it could give you a debuff such as you can't place attacking turrets for 15 seconds, then you could keep some consistency and still have to improvise in creative ways and can create certain debuffs for certain levels Songs aren't memorable and the game lacks a developed identity with the songs, I like to turn off the music of the game and play some music I like more I think that the hammerhead shark turret that sells turrets should be a tool available in every level like the shovel in PvZ but should have a kind of long cool down or maybe cost extra, allowing for more strats, but not able to be used for grim reaper again and again quickly
I do enjoy the game so far, though I have gripes with certain skeletons screwing with the controls and how you're able to play. The Graffiti Skeleton disables your ability to place towers and is able to either shoot their spray themselves or place cans around the field forcing you to walk circles around the spray. The only ways I've managed to play around it were the intended method of using a Zappy Jelly to remove the cans they throw down, or simply kill them before they can do anything. Its fine on its own like most skeletons (Or enemies in any tower defense game) But a pain in the ass to navigate around with other skeletons. Its ability to stop you from playing the game can become tedious when you're forced to either move through its spray or have one of your towers disabled/removed permanently. Its one of the few Skeletons that I dread not because it will be challenging, but because I know it will be annoying to fight against. It's never really threatening enough to counter on its own because the spray doesn't deal damage to you, is otherwise ineffective against other towers, and is fairly easy to go against in a vacuum. But whenever its in a stage lineup, I always have a sinking feeling that the stage will be worse with its inclusion. Thankfully there are many more stages that don't have the skeleton in so I can otherwise recommend this management td game. Currently the sea-creature variety in how each one plays makes it fun to play with. When you're not stuck with a ♥♥♥♥ ass skeleton screaming at you for playing the game.
I do enjoy the game, but since I've switched to a worse computer (Broke the other), I've realized its horribly optimized, so now I can't even play the game.
Amazingly chaotic
operation octo is a seriously good game for anyone who enjoys tower defenses it has a very unique format where you can run around the field and take damage and die the towers are all fun and interesting and so are the foes it made me feel joy and stress and frankly despite there only being 3 worlds the achievements are fun to get really my only gripes are the boss fights while enjoyable are not the best part of the game although still very good and the currency is a bit hard to grind but even then most of the extra stuff beyond the towers to grind for is purely optional overall if you like PVZ or other tower defenses like it this is the game for you its fun its quirky its cool its funny i feel like its a solid 8/10 has minor issues and it currently only has three worlds but im sure with time and updates it will rise in my ranking im really looking forward to its next worlds and i hope you try this game too and support it
I am almost done with world 2, and I'm really liking the game. Nice music, clean artstyle, and very fun mechanics. My only complaint is there isn't a config menu for controls, which makes playing on the Steam Deck pretty clunky (specifically, ZL & ZR are for Zooming in/out, but also place your two recharge special things).
This game is such a good get if you're looking for something to spice up tower defense with more real time elements or scratch that Pvz itch. It's got a great since of hectic without feeling unfair, and it's awesome to see towers that have so much personality in their art and animations. When I first played, I did occasionally run into bugs that broke the flow of the game a bit, but it's been getting pretty frequent patches, and the dev was responsive when I reported issues, so I bet this is less of an issue now. Also, you can give the walrus a wizard's had. Need I say more?
genuinely fun. i really like it.
