It's a great game that you can sink a lot of time into, but it's simply ruined by having to click "again" every time you die, which makes no sense because this is a keyboard only game. It becomes really annoying when playing the puzzle maps, where failure is frequent.
Also no arrow keys, it just seems kind of lazy to have 3 different control schemes and not one to be arrow keys, which some people are used to. I don't even see the point of the 2 other schemes, you can't be fast enough with a mouse to get far in the puzzles.
Otherwise it's a good game, would be cool to have different maps for arcade
