Currently on lvl 32.
Very fun game, entertaining, difficult but in a good way, good controls, fitting music (but not enough different ones).
And now, for some bug reports/criticism :
-: ice blocs are buggy. When you jump on or when you fall on one, the nerd will sometime act as if they were no block : he just falls through the ice block. Note that the nerd doesn't get stuck. If there is floor below he can just jump through. If there is a saw.... too bad.
-; you will die if you stand on the edge of a canon when it's shooting.
-: every single "rising lava/acid" level that I did (didn't try lvl 32 yet) had one horrible design flaw. When you start one of this lvl, you will quickly outrun the rising lava, giving you a sense of achievement and safety. But in every single lvl, there will be around the end an element of level design specifically here to make you lose time : destrucible rocks, mazes, turbo-lava... Basically, the game makes you think that you are safe because you put some distance with the scrolling, but it's completely wrong : two tiny mistake, or one missed jump and you are screwed. Even if the lava is two screens behind. It would be a fine (but mean) element for one or two levels, but they are all like that. In these levels, you are not racing against lava because it's not on screen : you are simply racing against time. Those time wasters are annoying as hell.
