This is a very good example of getting the core mechanic right despite the artwork. I would say you are more on the 'programmer' side of things compared to art. Idk how the top score is 488, my max was 100 xD Also for a moment it felt like i was playing a 2D barebone version of AimLab hahah - (cool idea for a game? shooting trainer for bullet hell multiplayer games or something )
This game has potential, 100%! :D well done bro!
