So let's talk about the negative point first. The music is... oof. There is maybe to much air control. The game is really not forgiving.
No let's talk about all the postive point.
The level design is cool, I really like the second level.
We have a great feedback when killing enemies, great job!
Controls are working well.
Hope you will polish it a little and it will be perfect!
By the way, no problem for the Azerty keyboard, when I build my games i usually forget to put an WASD keybord config.
