There's a game in here, but it needs a little more polish. There are some bugs like the coin count doesn't update and show you spent them till you lave the menu, you can fall off the map and you don't game over, just keep falling, and the game play feels very basic. It's a good start though and with enough polish it could be pretty fun, just right now in it's current state it isn't that fun to play.
A few other observations, if you get far enough the enemy can just land on your head and stun lock you till you die because you can't move and you can't aim to hit them, that really makes it feel unfair.
Edit: Good job on the sprite work, that's something I did like about it.
