if you're allowed to advance more than 1 wave at a time, and since you get to keep your experience even if you lose...you could easily just advance all the waves, quit, repeat.
so that's a ridiculous suggestion, but this is a good game. the speed up toggle is a good idea, though
i made... a meteor... 269 miles in diameter... i sneezed... on my cat... which lept up onto the desk soon after... i lost control of the meteor... i watched in horror as it flew up, it missed the f'ing planet...IT MISSED!
My mind fizzled as I tried to come to terms with the fact that he always ends up in the foreground. Soon I realized what to do, and the levels flew by. Perhaps some harder levels, and badges. Other than that it was amazing, I've never seen anything like it.
saves, and perhaps making it more like "Asteroid", by adding asteroids, and having 0 friction (friction, in space? srsly?). Make leveling do something, and make a separate area to fight npc's, so if you are continuously getting owned by someone, you have something to actually do
Chat Box: Let's you notify the creator if you're stuck, or something. Will also prevent some of the confusion I've seen in the game chat, as people try to figure out which of the 10 people with the edit key trolled the level, if you have a name above your head, it's kinda hard to pin the blame on someone else.
want to know how to beat level 24? add a bar on the second ball from the bottom to the LEFT, then, as it falls, quickly add another one so that it taps the square, simple
