Great game, very juicy, polished, and well put together. It has decent enemy variety too. It feels pretty complete and it doesn't look like you ended up cutting any corners.
The only thing this game is missing is a sense of progress. After about ten playthroughs, it became clear that each level was going to be the same as the first, so I didn't have enough incentive to keep playing, I don't even know if the game had an ending. If you just added one new obstacle on each level, it would probably have more replay value.
I don't know if the game has enough of an identity to compete with a game such as Spelunky, because all you have going for it is the bomb mechanic. It's cool you can speed boost with them by jumping, but I think it just needs more. Then again, Spelunky was in development for years, and you've had a week to work on this game, so maybe that is unfair of me to compare it.
Nevertheless, great job, I think if your going to develop this any further, you should explore more with the bomb mechanic and see where you can go with it.
