The game is hard - and that's fine in concept, especially since each run is only 10-20s long, meaning you don't keep losing lots of progress all the many times you die. That said, quite a lot of the difficulty comes from what appears to be dodgy collision - if you're anywhere near an enemy, you hit them, and jumping next to a wall stops you dead in your tracks. That said, the graphics are good, with some interesting monster designs, and I did enjoy it enough to beat it a few times to try and beat my, uh, time.
