I would have enjoyed it more if not for the moving mechanics. At times, it appears as if the character will teleport to somewhere (ex: I'll make him move left and suddenly, he'll be there without having appeared to move across the ground), so there seems to be a skipping problem. It may not seem like much more than an annoyance, but it is hard to judge how far to jump and how long to hold down the left and right buttons if the character isn't keeping up with it's movements. Whenever I went to jump, he would sometimes jump too high (I think it would sometimes do a double jump when I only pressed up once), causing me to hit spikes. I don't believe this is do to lag since I have a macbook and I don't usually suffer from lag from most of the other games on this sites.
Also, the music doesn't play for me. Still, other than these problems, this is a good platformer that definitely deserves a sequel. I would suggest adding more of a story though next time because it could add so much more depth to the game (especially since it appears that the main character considers the environment and his adventures to be "one fine day").
