Clicking the first time works and plays an attack animation, but then the character's walk cycle is frozen on one frame, at least I can still move. However, clicking a second time after that causes the character to freeze and I cant move anymore and must restart the game. Due to this bug, I cannot play the game to completion. Don't know if you can do any other movement besides walking (space doesnt jump, w doesn't go up ladders, etc). Art looks good and the music is nice.
