I'm beginning to think that slow splash and big splash are mid-term wave solutions and that instant death is the part of the final teleport instant death solution.
Start any later game with a star or two and make a pure of each type, favoring the star. Then a couple slows or confuses and a whole bunch of instant deaths.
I was enjoying the game, until there was a repeated sync error. The planes I saw, and the ones that the server saw were not the same, and so the weapon was impossible to use.
I used a maze with 3 sections, it worked very well. I used the boosters for the swarm towers on a bash tower to do the killing. I had room for 6 snaps or swarmers or additional boosters on the same layout.
Now for hard.
12256 on lvl 91. Spikes are expensive. If I was to try again, I'd probably try and get more swarms, which are somewhat cheaper... you still would need both.
use the 1 hotkey to kill... essentially everything that takes one hit. The first objective is to get 3 in more gold. Then a mix of mana and one of the first skills. After you max those three out you won't have any problems. Somewhere along the way you should get the trap too. Its easy then. Very easy.
