very very cool. Maybe you can use seedit to place some grass on the terrain. And maybe some dirt sprites in the city. But that won´t do very much to the fun of the game.

I can´t wait to play it! Keep it going! You know if you simply finish the game with all the levels and it´s ready playable and fun, it´s no big deal to add details like grass sprites here and there. (I think also that´s easier to find help if it´s fun.) I am realy looking forward to this!
