Sweet.
This game kinda reminds me of super smash bros melee because there are 51 waves and there are 51 events in SSBM. For some reason, the yellow pentagons were harder to kill than their white versions. The boss (lol) , which was the octagon was VERY easy... OH! And for anyone who wants to know what I used against the octagon its:
4 level 4 light towers
1 level 5 light tower
1 level 4 void tower
2 level 5 lightning towers
and 1 level 5 flamethrower
I killed the octagon in literally 3 seconds!
Other than that, good game! 5/5
