I really wanted to like this one. The kunai swinging is a really fun mechanic and it's done well. It's just that the rest of the game is not very interesting. The color palette is very simple which isn't a problem in and of itself, but combined with the fact that the environmental elements are also not all that varied means that most areas look pretty much the same.
Additionally, I found the enemies to be either trivial or obnoxious to deal with. You get knocked back every time you hit someone so you have to walk forward in between every hit (I know Hollow Knight did this too but it's much more dramatic in kunai) or you kill the enemy in one hit and there's no point. I got to the third or fourth area and didn't find any of the enemies to be engaging and the metroidvania style exploration to be boring.

Talvez o jogo mais sem personalidade que já joguei!

Quando falamos de metroidvânia, algumas coisas são bastante importantes, a movimentação (aqui o jogo acerta, na verdade a mecânica mais interessante do jogo está ao redor disso), os poderes (completamente genéricos) e o level design (atrapalhado, mal conectado, ruim mesmo).

Falta personalidade na história também, a arte é sem graça, a história parece inventada de última hora.

Pelo que vi, parei em 50% e me recuso a gastar mais algum tempo com ele.

I have very few complaints. Movement is fun with the titular kunai grappling hooks, the stylized look suits the game well. I did encounter one glitch that left me unable to progress in a late game area, but quitting and reloading fixed it, and the checkpointing was really generous at that point in the game. On that note, the checkpoints feel somewhat arbitrary in their placement at times. They appear very frequently, but oftentimes you'll encounter a platforming segment over instant-death hazards, and the nearest checkpoint is several twisting (but themselves unchallenging) corridors away, so any time you miss a jump on that particular gauntlet, you have to make a sort of tedious trek back to it. This isn't frequent, and the platforming challenges in question aren't really insurmountable, but it happened often enough to nearly discourage me from continuing.
Also, the dialogue and visual gags include a lot of dated (or very soon to be dated) meme humor, more worthy of an eyeroll than a laugh.
Other than those, all around decent.
