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.

太短了
There are not a lot of Touhou FPS games, and Lunarian Invasion is decent for what it is. There's definitely some jank and the level design leaves a lot to be desired. The lack of mid-level checkpoints can be annoying when you catch a stray bullet in the final room, and I wish the 1UPS functioned as actual lives instead of a health refill. But there's a lot of charm here too. The game especially shines in the weapon designs, enemy models and animations. It's a joy blasting enemies with Cirno fumo, and the sound design and music is decent. The combat is perfectly servicable, if a bit rough around the edges.

Минусы: - оптимизация - физика и передвижение потерпели большие изменения, увы не в лучшую сторону, раньше оно было более подходящим жанру - UI вроде красивый, но непонятный - Потеряна ламповость первой части, юнити был ошибкой Плюсы: - Можно запросить возврат средств
problems i have with the game i have played though it and their is a lot of fun to be had but their is only one problem i really have their is no pick ups like last game {example from the first game is the super shot gun under the waterfall} , i looked around and found nothing but this leads to having not a lot of ammo which would be fine if we could just find more but you can't i looked around. past level 6 had to finish the level with just the revolver which is a problem since most of the games fun is the fast pace gun play and only be able to use the revolver once all the ammo for my other guns run out is not fun since now instead of running and using dash's with stop time to clear rooms of enemies i have to conserve my bullets for a different room so i now have to play the game slow and methodical especially once you get inside the base since the rooms all have door so the most viable way to save ammo is to walk into the door and shoot and then walk back and repeatedly peaking the door to kill a enemy with the revolver which starts feeling very under powered since multiple enemies at the stage of the game can take multiple bullets to kill i love the game when you can take it fast pace and play with the guns but not having more ways to get bullets is making it hard to enjoy the gun play since it limits it what i would like to see in the future ways to like fix the problem would be to reward a bullet back if you hit a head shot or maybe have ammo box's that you can pick up or a melee attack that gets you bullets if you hit a enemy with it or just have give the player more ammo from the start but this is not the best i feel a melee knife attack that gets you ammo for the gun your holding would be fun reloading problem. this is only really for the fumo and the p90 since their reloads are the longest i would love it if you were to dash with a empty mag on the fumo it would reload it so you can really have fast gun play i find myself shooting a mag dashing to avoid bullets and then reloading which slows the gameplay down make the revolver more strong i feel it is under powered in later levels which a problem since you would have to fall back on it alot now i love the game series i played 1 and the dlc i think the developer will make this a really good game given time right now the game is a 7/10 but i think he will make this game a better one given time i hope they don't give up on this game since i love the series and i want to see it reach its real potential as i like the switch to 3d i want to see them really succeed in making this a good game so i will keep playing it i just hope they make it more fun also i love the rag dolls <3
So, I've finally decided to give I Am Sakuya's sequel a try, and yeah, it still feels like a badly made Serious Sam clone even after all the updates. I am recommending the game though, even if it's inferior to the prequel, because the developer is still actively updating and improving the game, step by step. - The game feels REALLY choppy, like im playing on 60 FPS even if i set my cap to 240 or unlimited, with or without VSync. - The time resource is so limited I rarely ever used it, just because of how limited it was. I don't understand why the time freeze is so unimportant in this game compared to the first one, it feels like it's not the main focus of the game, even though that's Sakuya's entire gist. - Grass floating on the sky level. - Using CTRL (time freeze) works even while in the visual novel part of the game. (wastes your resource) - The boss spawns in orbs even while time is frozen, which disappear after unfreezing time. - Textures clipping on the climb up to the tengu castle thingy. - Shotgun is basically a sniper rifle. (it's very funny) - Pathfinding is so messy on the level after the boss, units cannot ascend/descend small slopes. - The escape menu closes a second after clicking escape but the game unpauses immediately. - One of the mobs dashed into an object, making it stuck in place and unable to move. - Lots of floating objects on like 50% of the levels. - Doors are hard to see in the later levels + they stay closed even if im nearby. - Enemies detect me through walls and start shooting nothing. - Enemies also have trouble going through doors constantly. - Frequently i get a random slowness effect on me for no reason for like 2 seconds. - There's no feedback on saving the game - you don't know if it's saved or not, no "The game is saved" message, nothing. - On bosses, I use up all of my secondary weapons and get the boss to 50% health and the rest of the fight i am forced to use the revolver to slowly kill it.
games decent but needs polish, the dash getting stuck on defeated enemy rag dolls some invisible walls stopping me from shooting enemies (most notably in the lunar market) subtracted from my experience but it was otherwise a fun game.
Switching to a positive review with the caveat you should probably get it on sale, the developer has been slowly grinding away to make it a much better game. I respect the lengths they went to make their game better after a rocky launch, with more on the way.
Compared to the prequel, this is a massive downgrade. The maps, enemies, everything just feels bland. You get every weapon right at the start, and there isn't much to explore. The game overall feels extremely unfinished. However, to list some positives, the dialogues are VERY funny, and the timestop mechanic works way better than in the prequel. I also LOVE the little dash Sakuya has. Overall, if you loved the prequel, you might like this one as well, but until this game gets the bugs fixed, and the "alt fires" for the guns, only buy this if you're a huge Sakuya fan with nothing else to play.
If I AM SAKUYA is so good where is I AM SAKUYA 2... ♥♥♥♥♥♥♥♥♥
