So I spent 2 years trying to complete this game, trying to get the achievements. I've grown to love this game, and hate it at times too.

This isn't just your typical rhythm platformer, but it's one that's filled with bright colours, pleasing aesthetics, and above all music that feels as though it's as much a part of the game as the ground, enemies, or player character are. The game will captivate you with it's charm, all the while making sure it's got you tightly enough that dying at particularly hard chokepoints don't scare you off.

It has a good learning curve, though seems to stop short of it's full potential. The 3 levels of the game are well designed, but can be quick to punish you if you are impatient. Of course, the checkpoints make sure you have a chance to attempt the hard parts very quickly again.

The mirror levels are the frustration point for the completionists, and where I feel the real challenge lies. You do the same 3 levels as before, but the opposite way and no checkpoints - if you die you go back to the level select. The game will punish you again and again, and only reward you for persistence, patience, and practice.

Overall I love 140. And I'm sad that I'm not going to be able to continue trying to beat it.

2020 Edit: Level 4 was very interesting. I look forward to spending 2 years trying to beat the Mirror Level.
