This game is really cool. I love the visuals and the audio, they all look great! The game is pretty fun. A few points of feedback from my point of view, I dislike all the options for jumping and shooting. I think space would be a good jump button. But even after playing through it twice (without beating the boss, probably skill issue) I couldn't remember z and x. As well, since you said it's a game focused on speedrunning, I'd make ways to make you feel faster. Like when you kill an enemy, the energy you gain also boosts you or something. The dialogue was good, but maybe more spaced out (or in future levels being decreased) would be great. Other than those pain points though, the game was great and felt really good, so major props!
