Pretty good arcade game to play for a few minutes but needs more polish. Hitboxes need a lot of work and a way to get back lives would be nice. It would be nice if you could fix the enemy spawn locations and movement patterns a bit because sometimes too many will be present in the area where the coin is and it becomes nearly impossible to get the coin when that happens. With some polish, a leaderboard system and a few other twists this could become a pretty decent arcade game, but it's got quite a long way to go.
i have made a dozen games, far better and more polished than this, that i still wouldn't upload to NG.
