This game is an absolute gem. The presentation and concept are fantastic, and the gameplay is really fun. You guys did a great job. That said, I do have some feedback.
First off, King Mode was not a good fit for a platformer, at least not the way it was implemented. It was so hard to control that I usually ended up just committing suicide when I rolled it to save myself the few seconds it would take to die anyway.
There were certain modes that just were not a good fit for one another. The combination of recoil mode and retaliation mode is a good example of this. Having to propel myself with bullets in a level full of spikes and enemies while projectiles were being shot at me led to a lot of deaths that felt less like I messed up and more like the game just decided it was my time to go. This was a problem quite a few mode combinations suffered from, especially by the end of the game.
That wasn't the whole game though, not by a long shot. When the game at its best it was tough but fair and extremely satisfying. I think the only difference between this game and one I would pay actual money for is a little more time in the oven to tighten up those modes and make some more levels.
I beat all 12 levels and had a blast doing so. Seriously fantastic work, guys.
