Thank you very much for feedback, there is a lot more to fix then just those 2 things. My biggest mistake was that i got too ambitious and i had 0 time to playtest. I am definetly going to make after-jam version of this game.
1- is definitely easy to fix, good tutorial and hitmarks will solve it all
2- for the two i was thinking that the player should slowly get more speed, so you can quickly fly through already cleared areas (or maybe checkpoints along the way, that would be cool)
oh and the weapons are waaay to expensive
