Okay, so. This platforming and movement is spectacular. It's so satisfying to pull off the transform-launch-transform every time you do it and (most of the time) the deaths that result from it are a hilarious learning experience. The combat was a little hit and miss though. The projectile and explosive enemies were nice and meshed well with their environments, but the ones who rush you, the boss included, felt really off. I think it's because of how fast they move in comparison with the short delay it can take to get yourself oriented for a jump, but it's hard to put my finger on it. I tried counting frames on the boss, and the delays seem reasonable, but I found the dash extremely difficult to dodge. I'm really not sure what to suggest there, but everything else is outstanding!
