Heyyo, thanks for playing! I appreciate the feedback, and already have something in mind (by recommendation of other players) to ramp up the difficulty in a performance-sensitive way in a post-jam update; more dogs and plague mice! I'm also playing with the idea of ways to counter-attack Waffles (jump on his head), and other power-ups (instant laser charge) to compensate for the new difficulty curve.
Trivial or not, 40 points in no small feat. Would you say, higher than the Dev Score? 43, perhaps? I'd post a link to your jam submission on the game page for the remainder of the jam, if that were the case. Something you'd be interested in?
