Nice game! Here are my feedback on it:
+ The art style and the universe are nice! I like this kind of robotic atmosphere.
+ The different type of enemy was cool!
+ The movement controls felt responsive.
- When we go left or right with the character on the ground, it feels weird, indeed, it seems that the character rotates on himself in order to flip on the good side.
- For me, it misses feedback hit on the player, and enemy, so it was hard to know when I got touched, or hit well the opponent. Moreover, I noticed that I can be hit while moving in another scene, so I died a lot of times because of this, which was quite frustrating.
Overall: Good work!
