Really hard game. I have a hard time figuring out what the A/D controls do and sometimes the character seems to hit an invisible corner, taking away all speed. And the jumping seems random. Sometimes you jump high without forward momentum and sometimes you jump really shallow at full speed. I played quite a bit, but did not manage to clear the first level...maybe just really bad luck/lack of skill?
The graphics are really nice though and I like the art-style. The sound effects fit the game well too.
