Incomplete
I think this game needs a little more tweaking. Especially with the AI enemies. Most of the time I couldn't tell if they were chasing me or aimlessly roaming through the levels. And there were some levels where it was impossible to get a coin without getting hurt(22, 32). Also, some level designs were a little too much when it really wasn't necessary and other levels had enemies in unreachable areas(deeming them useless).
Overall, the game is a good timekiller and I love the design. I wish there was more stuff to play around with. The bombs were only useless for like 10 levels(sometimes I forgot the game even had bombs) and there were no power-ups. Every level had the exact same concept, which makes it boring after a while. Learn to switch it up a little bit. I can understand why the game left half-done. When you know you're close to finishing something you worked so hard on then you start half-assing it at the small things... but those small things do matter when it comes to the finished product.
Last piece of constructive criticism(or complaints for the pessimist): I wish I knew how many levels were in the game. It makes me feel better when I know what I'm aiming for. Since I had no idea how much longer it was and I grew bored after the same old thing, I quit on level 37.
