Consider buying if it's on sale for <$5. Great premise and idea but heavily flawed.
• Very little content, you've seen basically everything after a few runs—you don't even have to get far in the game to see all the content.
• Randomly generated levels are decent but limited, with pretty much all levels being just a square with terrain raised or lowered in some spots. Occasionally a more unique level will be generated though, so it's not too bad.
• NO mod support at all! This hurts the game a lot due to just how little content there is.
• The second (and, I believe, last) tier of enemies you encounter every run are very frustrating to fight against.
