I like the choice of visuals a lot and the mechanic felt very clean right away. The gameplay is really well done with the different collectible upgrades and temporary abilities and it kept the game a lot of fun! One thing to improve it could be that I think there may be some unintended bugs. For example, I think I was not able to die or get hit anymore, at all, even after invincibility wore off, making the game a lot easier but maybe that's not intended.
