Half the game is really fun and clever puzzles, the other half is the most aggrovating trial and error bullcrap. There are barely any checkpoints on most stages after 15, and failing a platforming section kills you. Why? Shouldn't falling down and having to redo the section be enough punishment? Apparently not, cuz the game forces you to restart from the last checkpoint for whatever reason. The checkpoints are optinal, if you want a bigger challenge, just don't use them. So why aren't there more of them? Also, 1 hit and you're dead with no way to increase your health, not even in boss fights. Now that's what I call fun game design! I realise the game is from 2010, and getting this worked up about it is pretty pointless, but when I first started playing only a few days ago, I had really high hopes, sinces the first 9 stages or so are really great! Everything beyond that however, is mediocre or plain bad.
