I found a really fun glitch on this game with my son:
If you keep 2 cars on top of each other, on the exact same coordinates, they never fall and go away to happiness together :)
I installed it from Google Play yesterday and loading was stuck on the first time. Restarting worked.
I totally agree with you. Different enemies with different attack patterns would be great. :)
looking at the examples, it sounds fine to me. Also, previous Game Offs always mentioned that the theme is loosely based on a word, and by the examples given I think this continued true.
