Movement is very janky, like probably would be better instead to make it without rotating and instead just go with more straight forward option of just moving character in direction of WASD press and just rotate ship depending on normalized direction. Also some sort of safeguard for upgrade window should be added, or at least a bit of delay before you can press upgrade buttons. 2 out of 3 times I pressed it bu accident. Other than that it's amazing game. And you get almost everywhere minus audio 5 stars from me.
