From main menu, for free money:
Click play, put all skillpoints in $, go to the hardest wave you've unlocked, click esc then main menu, repeat. You get the $ for the wave you started even if you don't complete it
On level 18 I first used the balloon to remove the block but since the level didn't finish I tried putting the bomb on top of the block and raising it a bit with the balloon.. The bomb exploded and literally didn't move the block at all. 4/5 for fun
This game is just too slow for me. I build my towers, get them to level 2-3 and then leave it running for a few dozen minutes while I do other stuff, and I always win without letting any of the enemies get past. It needs to be faster or more difficult, or both
