This game is okay, but there some things that I think It should be added or fixed in the game:
1. The buttons W,A,S,D should be the main moving controls and the arrows the alternative controls, because much people are right handed and some are left handed. I know that W,A,S,D are used with the left hand, but it's because that we need to hit quickly and consecutively the space button to make the character moving faster.
2. I don't know for the others, but when I make the character going down the screen while I hit the space bar, he dosen't move faster. This need to be fixed.
3. Add a restart option because it's boring to quit to the main menu and then come back again.
