I really appreciate the feedback! Yeah, the levels are not very challenging and reasonably open-ended since I've had plenty of bad experiences making and playing tough games for a jam. Everything you mentioned is really good stuff to think about (as far as score, we were talking about implementing a speedrun timer that'd be shown in the top right). There's so much else to mention that I don't feel like cramming in this one comment, but there's a ton of things that can be done here, and it's all under consideration. Working on this into a full release is becoming more and more of a possibility.
