Enjoyed playing this. In particular, the little touches of humour and incidental stuff (like the slow motion button). The character controls very well too. I ended the game when I got stuck behind an orange background though! I think it was the third level, where there's a big drop and I went through the floor. I wasn't too much of a fan of the fight mechanics or the randomly dropping squirrels. The traditional Mario-style jump kills would be better for me- especially as the jumping is very good in this.
One thing that might confuse people is the presentation style- I assumed it was going to be a mobile-style platformer at first, with single-screen levels you complete in about 30 seconds (partly due to the level select screen). Instead it's more of a quest-based adventure. This is better for me, so I'd recommend emphasising and enhancing the adventure aspects of this. Or not- it's your game after all- do what you want ;)
