Okay, I've found a simple, but EXTREMELY important bug: when you sell something, it doesn't disappear from your inventory, allowing you to sell the same object multiple times, giving you unlimited research points. This kind of ruins the spirit of the game, although even with unlimited upgrades, the last few levels are HARD with a capital "H".
On level one I scored one billion, two hundred eighty-seven
million, eight hundred fifty thousand, seven hundred forty-nine points.
(@thechuzzler: it sounds better if you write it out, instead of using numerals.)
Addictive, great graphics, interesting and original physics, great game. But TOO SHORT! NEEDS LOTS AND LOTS OF LEVELS! Also, it would be interesting if the nuclearoids turned into bigger nuclearoids when they exploded, simulating nuclear fusion. 5/5
Very good programming style game, but there is a big problem: it doesn't save your solutions, so if you solve a level, exit to the menu, and then go to the same level, you'r solution is gone. That's a very big problem. Other than that, I just have a couple suggestions. For one, more functions (and\or bigger functions) would be nice. Also, in addition to plain old function calls, there should be return points, so that you can return to a certain point in a function, as opposed to simply returning to the beginning.
The gameplay is repetitive, laggy, and, frankly, boring. If it were something other than twenty levels of pointless climbing, I might be more generous. As it is, one star.
Ok, i've found a bug. I recently solved the robochildren level, but when i load somebody else's solution, the malevolence engine claims it "saw what i did there" and says i cheated. I'm not complaining, as it doesn't matter anyway, but I just thought I'd point it out.
