Dude, stop stealing sprites from ROTMG. There are lots of great sprite artists on NG. Also, I think that deadline with boss might be a little bit longer.

The game is quite amazing. I like that perfect mix of cyberpunk and fantasy. I have thought, that something like this will not end well, but it did! Anyway difficulty is fine, but it needs something to refresh the gameplay, something more than just adding another class.

There is still a lot of work to do. I suggest to improve graphics (25 minutes with Gimp), give it better music, (30 minutes with LMMS) so it is not like horror movie and make it in English please. This may be an classical arcade platformer game.

Very good one....
