I am experiencing crashes with the very same combo, thought it happens closer to last wave. I like going for one particular tower and creating a bunch of this very same tower. A lot of them made me lag, particularly the Laser tower and the Comet tower, because of their projectile type. Only the Laser tower made me crash, and that was at wave 61, when I bunched them up. However, Tsunami is the only tower to make me crash before this wave. I've tried doing it all the way to the wave 61 three times. All three times, I had 12 Tsunami Towers set-up along with 3 Fountain tower because it's with the same element and synergizes so well with Tsunami. All three times, I was in the process of preparing to spend my money for wave 61 (building a bunch of level 1 towers). And all three time, Starcraft crashed on wave 58 (Darkness + Mechanical wave). How it crashes is that Starcraft freezes, then it just closes. Nothing else, it just closes without any change in the frozen image. No error notification or anything. I believe it can't be because of the lag, because Tsunami's projectile is just a laser that goes straight to the target, with an explosion once in a while. I've managed to survive over 50 Comet Towers on wave 61, with their 7 slow projectiles per second that move in a wierd pattern, I don't see how I wouldn't be able to survive 12 Tsunami towers 3 times in a row and on the very same wave.

Comet indeed seems to be really powerful. I did something similar, where I used a bunch of Comet towers and built a Deceit tower for every 4 of them. It was extremely lagtastic, but worked surprisingly well for a tower that does not deal damage in an area. I've been having fun with all dual towers, as in going only for one specific dual tower (and adding single element tower if that tower was a support type like Deceit), and as soon as I went for Comet, I easily doubled my record of fruit kills. Also, normally, I had trouble with waves that resisted my dual tower, but with Comet, the only time I leaked was once at the beginning because I did not have any triple tower set-up yet, and 12 lives at wave 59, because they were earth, but also because I was so focused on getting my towers ready for wave 61 that I did not upgrade my defense at all for a long while. So yeah, seeing how you were at Very Easy, managed to fill up the map without Deceit towers, and increased their attack speed with another tower, it does not impress me that it's able to score infinite fruit kills.
