Very cute game! I completed all but two levels with just one bot and that definitely seemed like the most fun version of the game.
On those other 2 levels, the one where you had to pull a thing I and it seemed like a fine introduction to the mechanic. Then we get to that one level. There was one level where I am pretty sure you were supposed to make a bridge across a long gap. I must not have understood a mechanic because this seemed impossible. I managed to get past it by discovering a bug. If you self destruct enough/fast enough you end up summoning more than one bot at once. Eventually I had like 200 bots out and could walk across their corpses to victory. Note, this also created a lot of lag, do not recommend.
That one level aside, the game was fun and the art was cute!
