The 3D pixel art converted characters turned out great, the animations have a really nice flow to them! The tileset environment is also looking good, it really captures the sci-fi atmosphere.
I admire the sound design! The ambient and moody music track fits the environment and puzzle gameplay very well! The creature sounds are bizarre and seductive, I love them!
Puzzle gameplay is fun and easy to get into, I would definitely like to see the concept expanded with more levels! I don't mind the slow pace since the levels are quite short, but some of the segments are somewhat demanding in terms of precision. If you want to expand the game, I suggest letting the players unlock several levels at a time, so they can choose to skip any that they're really struggling with.
Nicely done!
