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/day in the week to Aug 8 → 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.
About
Towerix91 is an incremental tower defense game in the style of PC games from the late 80s and early 90s. The interface, styled after old operating systems, creates the atmosphere of a classic strategy game on a vintage computer.
Different types of crystals that drop from enemies are the key to leveling up. The branching upgrade tree offers dozens of options, where each branch splits in two, and the chosen path determines the strategy. More powerful upgrades require rare crystals, which forces you to think through the development of towers and the use of crystals as temporary upgrades during waves.
Towers are placed along walls, their abilities are combined, and special skills and upgrades are used to repel the growing waves of enemies. Defeated enemies leave chests with temporary upgrades, gold, or debuffs.

Solid little tower defense game that's leans much more towards the easy side. Game doesn't take too long to 100% taking me ~2 hrs to do.
A nice little incremental tower defense game that is worth the price. The game is not very long and really easy to get into, I failed only a few runs before getting the hang of it.
Прикольный и довольно таки замороченный тавердефер. Очень олдскульно, для особых ценителей)))

very nice, although once you max out the upgrades it's a little bit too easy.
[quote][url=https://store.steampowered.com/curator/33401179/]Follow my curator page for more recommendations![/url][/quote] A nice, short tower defense game with some incremental upgrading. It took me a bit under 4 hours to buy every upgrade and complete all 10 missions. After completing a mission you can keep going infinitely with challenge waves, which I always did since they give extra crystals. There's a decent variety of towers, 5 total with each behaving very differently. imo the best were Frost, Knight, and Inferno. Berserker would've taken Knight's spot if it had better range. There's quite a few enemy types as well, but I can't say I really know the difference of how they behave other than that some have shields, some are invisible to most turrets except Frost, and some are big sponge-y boss types. I would've liked if there was some sort of tutorial, it's a tad confusing at first. Some sort of "bestiary" in the main menu where you can read up on the differences of each enemy type would be neat. The first level was also very difficult until I was able to get quite a few upgrades going for Knight, but the dev has already put out a patch rebalancing that level so I imagine it's fine now. Dev seems very open to feedback. For example originally there was only one volume slider that affected music and SFX together, and I asked to have those split up and they very quickly patched that in. The music is actually one of my few complaints with the game, it's okay at first but it's incredibly repetitive. Most songs are just short loops repeating forever until you switch to a different mission. It'd be nice if the game instead randomly played all the songs in the game rather than just one per mission. I also liked the "between waves" music more than the combat music, would've liked to have heard those tunes during combat as well. My only other complaints are pretty minor, like how it's unclear what some upgrades, enemies or modifiers do, and that the treasure chests have a chance to destroy a tower. I just don't think that adds anything fun to the game, and whenever I'd get hit with it early on in a mission I'd just restart because it basically ruined that attempt. I'd like to see some form of endgame where you can infinitely upgrade turrets, maybe some bigger levels (combine multiple into one final endgame map, perhaps?), but even if the game doesn't get anything like that I'd still recommend this for the $4 it currently is on sale for if you enjoy tower defense games.
Trash tier with the depth of a game jam dropout. Pros: Short (2.4h for a full completion). Cons: Not short enough to refund. (Well, my bad actually — forgot to shut it down when I went to eat, but still). Has a price tag. Seriously? $3 for a product less consistent, polished, and packed with content than a whole lot of free stuff? Sold as a final product despite having obvious bugs, such as skill buttons going below the screen on an upgraded "tower" or misnumbered counters on fully learned skill trees (consistently showing 6/7 when there are only 6 levels available). Randomly spawned chest drops with a highly irritating chance to destroy a random tower... and there's an option to pay to skip it? AND they just despawn if not clicked? Who the hell thought this was even remotely adequate mechanics?!
Nice fun 3 hour game. Doesn't explain much, but a lot of things are self explanatory.
Good game.
A short and sweet little tower defense game. The demo was fun, but the $4 was worth being able to complete the game fully. 9/10 The only thing I could really ask for is more levels, but that might require more upgrades and/or abilities, and that may not be worth the dev's time.
....this is 4 out of 10. why a thumbs up? theres a lot of potential???! cons -w/o any upgrades, i opened a chest which deleted my first tower on failure, which causes the run to end, really. boo!! -chests (always?) have a chance to delete the closest tower. they also cost $ to...avoid? to back away from? pro: theyre otherwise...upgraders, free money, free gems (upgrade meta tree and spells. and 1 level modular enchantments) con: they only appear in the first few waves. usually 3/12 waves. 10 levels, endless. etc. well. not much more for etc. -upgrade trees are...good but unevenly paced. green guy gets green gems rapidly (its a flamethrower tower. it just looks like a green berserker throwing axes or something, i wasnt paying attention i was watching...cheers? and some rlm, as always.) um. and yeah green gems get you a full kitted out green tree. you can convert gems, if you must to others. pro and con: you can finish the game in about 2 hours, or a dedicated hour or something. i wasted (at least) an hour on endless. this game can easily add a bit more. extremely tempted to give a negative review, but completionists might love it. i suppose it is NOT good value for $1=1 hour of fun? but im in au, my $ is different here, theyre golden coins
