A+ pixel art. Looks like there's quite a lot of content too.
Need and FPS limit option, I had about 1k FPS in menus and 500+ in game which is just a waste.
SFX volumes need tweaking (and a dedicated slider option), also when using the "super move" it can get very loud when lots of enemies are killed.
Having to sit through the cutscenes every time you die on a boss gets really annoying.
Pressing B on a controller doesn't always go back like I'd expect it too, it does in some menus but in for example the ESC menu its select. Made me accidentally restart a level.
The Helga fight is extremely annoying with the super fast, hard to see projectiles.
Didn't have to fight Helga after I had restarted the level? Maybe because I had changed difficulty from hardcore. I changed it mid game, if you can't do that I don't think you should be able to. Also having hardcore be the default diff you start with is probably not right. But I also have no idea what difference it makes, it really should say.
The plane fight in the first level felt waaay too long when it doesn't really change, its just dodging the machine gun girl's fire.
It feels like fast projectiles are generally harder to see when on a high refresh rate. Played on a 165 Hz monitor.
Some health drops would be nice, as its very punishing to die.
