Good: Generally solid controls, charming graphics. Awesome cover image.
Critique: I found the main level's central troll (the mid-level ones which I'm deliberately not explaining) a bit obscure for having 10-20 seconds of buildup beforehand. (Others are welcome to provide different feedback, but for me, another judge had to basically explain to me what I wasn't getting.) I realize part of the fun of a troll-game is being able to keep some information hidden--however, in this context, a closer-placed hint might have helped. There's a little mechanical jank here and there when hitting sides of objects that collide, but for the timeframe it's certainly forgivable :).
Thanks for entering! I really want to fight (or fight along with? not sure!) the giant muscle-dog. Let us know when there's more, muscledog or not
