Cool vibes, nice visuals. I like the backstab mechanic but the animation is too slow and the start is very unclear, just feels like you are frozen. I finished the game I think? Ended up back at the menu. The enemy mechanics are cool, the first encounter you have with one teaches you to be very afraid of them heh.
The pacing feels a bit weird after you get the dash ability. I ran into the next area after the dash puzzle and fell down a long ways and went through a bunch of different looking areas that all looked like new biomes, but then the game ended before I had a chance to explore them.
Good hinting on the "puzzles", you would encounter a room, try to do it, see you were obviously missing some ability, and backtrack.
Mentioned by others but there is a softlock issue I ran into several times where exiting a room right as you enter breaks things. One time it happened I was able to still move left and right even though I was off screen. I suspect the player is falling off the map.
Anyway nice work, solid entry.
