This was pretty good. The art was simple but endearing, and the calming music was a nice choice. Timing was a little tight on some of the movements and I found myself waiting for a while for a chance to move, but it was fine for the most part. I did end up with a situation where the first enemy would only go as far right as the ladder and I couldn't get past him, but that fixed itself when I died to him. Maybe reduce the randomness of the barrels and enemies a little bit? The one thing I would definitely add is a checkpoint after you beat each level. I barely got to see level 2 and didn't learn how to avoid the traps, and I don't want to have to go through level 1 all over again just to try again. That's the one thing I thought was kinda bad though. The rest of this was fine, good job.
