I would like to add that part of the problem is that there are no stats on towers or enemies, which makes it hard to figure out of I'm doing something wrong, or I just have to leave the game running for 10 hours to brute force a level. I think if there was some hint on enemy vulnerabilities or stats on how much damage each tower did or something like that it would ease the level 20 - ...
