Clever, challenging gameplay
4/5
This game really grew on me. It takes a moment to get used to the game mechanics, but once you do, it's a really clever and well-constructed game.
First of all, your graphics are perfectly suited to this concept. They're simple in design and color schemes, which helps keep things from getting too confusing. I've always liked your art style, and the game is really reflective of your work in general. The backgrounds were simple and clever. The main character and the enemies are very clearly delineated and well-animated.
The game mechanics, while a little unusual, become completely natural once you get the hang of things. It's not your typical side-scroller, that's for sure. Later on, the game throws a few curveballs with the different environments and a couple of different activities (the switches and the final race). It's a credit to your programming skills and the game's learning curve that it's easy to figure it out. Probably the only weakness would be the somewhat loose hit detection, especially when rounding corners. I bumped into several enemies even though I seemed to be far enough away. But it didn't hurt the overall gaming experience. The level of challenge was perfect - it wasn't overly easy or difficult.
I loved your choices in music - it really set the mood in each level. The whole game had a great mood and feel. I'm giving you extra credit for creating a nice storyline to frame the events. It wasn't tacked-on or gratuitous, and the ending was surprising yet made perfect sense. Nice work here. I wonder if you got your inspiration from dreams or maybe you're just a little insane. :)
Now after all that gushing, I do have one major gripe and I saved it for last. I was really annoyed by the keys used for the controls. A, W and D are not the optimal keys for this kind of game. Most games of this type would use the arrow keys and/or space, or allow customizable controls. The way it was set up here was awkward. But this is a very easy thing to fix.
Overall, I was really pleasantly surprised by the game. It really grows on you - and I thoroughly enjoyed it. I've always enjoyed your animated work in the past, so it was nice to see you put your visual stamp on a game. Great job!
