Before I gave this review, unlike most of you I played through the entire game. Using my laptop mousepad, I spent hours n one of the most challenging experiences a gamer could ever go through. The game is insanely hard from start to finish, which is why it gets three stars, but the real problem with this is one thing: lazy programming. This was made for stencyljam 2012, a competition I'm assuming very few non-developer newgrounders like myself noticed, and because of this the program used was not flash, but stencyl. This likely means more than a few things. First, stencyl is similar to scratch. Having used scratch, I know how hard it is to program some of the most familiar concepts into it. Stencyl being a more advanced predessessor, would likely have the same problems, but in less simple concepts. The creator likely didn't intend this game to be hard at first, which can be seen in the last battle since Arthur doesn't hit all the way at either side of the screen, showing some restraint. However, he obviously did not take the time to create a health system, and seeing how it could be moderately hard without messing up the game's difficulty or creating "stuck under the spike wall" situations, they opted to just not have any health at all. Anyway, it was fun at times, frustrating at most, and had some interesting bosses. In fact, this is overall a very good spin on the rampant physics games of today, but should have been at least playtested by the developer before it was published, because many of the levels need to be completely revamped, such as air attack, any level with blocks, the bottle level, and the caterpillar level, which really should be a boss. In fact, this game is about 60% overtly frustrating boss battles, some of which aren't described as boss battles for some reason (caterpillar, tractor, I'm looking at you.)
