Has so much potential, but in later levels makes the fatal mistake of substituting difficulty and ingenuity for fun.
+ Controlling Gish (a ball of tar) and using his moves (like having spikes come out of his body so he can stick to walls) is actually quite fun. The problem, however, is that the game quickly trashes everything that makes this fun and forces the player to make incredibly difficult maneuvers in order to reach the end of the level. If more focus were spent on the puzzle aspect and less time were focused on hazards to kill the player this game would be so much better.
+ Weak and uninspiring. The story just seems like a veneer added as an afterthought to give the game some reason for progressing, which is not what a story in a game should do at all.
+ The animations of Gish are actually quite refined. The graphics of the levels and enemies, however, could be improved some.
+ Hardly any. There are hidden areas to most of the maps and coins to collect for a higher score, which I do appreciate, but after dying dozens of times on each level I had no urge to replay the level or the game again after I beat it.
