F3--> "Fetal form of fun." give the upgrades some info, repair the bosses (boss 2 does nothing etc.) compensate for loss of income when one hitting earlier bosses, and this will be a fun little game. :)
This could be really sweet with some mouse control. I never made it to any shop. Is there any? The bosses are fun too. Too bad you lose you power-up upon hit. Could it make you get stuck at a boss?
Thank you very much! ^^
