Castle on the Coast is not the most engaging and innovative with its floaty controls and wonky physics. I found the jetpack early on and found it to trivialize most of the game, to the point where I almost wished that they hadn't included it as a part of the main game (it could have made for an awesome easy mode). The level design and characters are cute, however, and I did enjoy tracking down all of the game's "stars," so it definitely succeeded in evoking an old-school collectathon. It just could have done with a bit of polish!
