Thanks!
I think the fact that I played it in a larger size might have affected it a bit, in a small size it feels even more chaotic.
About rebirth it is normal that you are barely able to see it... I wanted to make it more obvious, but I didn't have much time to dedicate to the jam. There are stats that get better on "rebirth" (you are faster, have more stamina, shoot with more power, etc.). But the change is not very visible, because the initial stats are more than enough (and in a small canvas size even less important xD)
