Thanks for all the great feedback! Sorry about the installer. The only options I was getting were for a .zip file or an installer, and for some reason it wasn't letting me upload the whole .zip file. Next time I'll try to see if I can get that working, since (in theory) I won't be so pressed for time to get my game next game posted.
I've been getting a lot more clarification on that issue with the jump lately. I'll see what I can do about patching it, but I can't make any promises at this point, given that it might require redoing a lot of work.
The boss has a very short window of opportunity where you can hit him. It's subtle, but you can see a visual cue when he stomps down if you look closely. I'm beginning to think I made it too subtle, though (it was hard coming up with something I was happy with that worked with the limited color palette). I'll see if I can improve this in the patch, too.
I'm glad to hear you liked the game overall! Not sure what you mean about a 15 melon gate since there were only two in the game, but otherwise thanks again for the feedback and the kind words!
