As a game, its pretty darn boring. As a concept, not bad. Add some better graphics, a menu, some powerups, and some upgrades, and it may even be good.

I kept an open mind with this game despite the poor graphics. The gameplay could be surprisingly fun but the deaths just don't feel justified likely due to sloppy programming. However of the REALLY poor graphic games that look so bad you could barely call them games this one is definitely one of the more fun games that do at least have a playable element.

Well, you have the concept, but the game itself is not that good, it seems as if you did not have anything else to do so you did a game without a purpose, not even because you like it.
If you could have improved the animations, added some background and music, it could have been a waay better game. Believe me I tell you because I have been in your position

not bad, but you cant exactly move fast enough to get past red coins .

Fix your game up a bit. Add some menus, optional instructions, and practice making different types of buttons and improving your art work. Expand on that and this game would be better.
