It seems like a good concept but its obviously incomplete, there's no music in the game and some of the jumps (specifically the one after falling through the tunnel) require some extreme precision. What really hurts this game the most is the lack of a checkpoint system, I got about 8 screens in before I fell down a hole and ended up right back at the beginning of the first screen, I highly doubt that was a design choice. Also there should be some kind of way to know where those bottomless pits are, you don't need a neon sign that says "don't fall here" but something so that when you jump it isn't like "you thought there was solid ground down here? lol there isn't."
Overall this game is playable but I can't honestly say it was fun.
