I find I can't really do anything meaningful.
When the enemies show up, they merely shoot you to death, and that's it.
Rolling at them to eat them doesn't work, because they harm you far more than eating them helps you.
I never saw the "A" of R-O-L-L-A, or maybe the 2nd "L". Maybe they're too hidden by buildings?
As nearly as I can tell, the "special" can only be used if the "rage meter" maxes out, but this is not explained. Does the rage meter onl fill up when you get shot? Sometimes a power will go off, but I did not press the button. Did I roll over a power-up that doesn't look like anything special? When the special goes off, it ends in mere seconds, so it doesn't actually help. The "dash" doesn't dash at all, so that's just a lie.
There are no useful decisions I can make as a player, because nothing especially helps. The goal items of tower and firetruck don't especially grow the monster, and neither do the letters.
It's not clear if a smaller monster can eat a larger building when given enough time, but the enemies show up so fast and are so deadly that I can't even hang out to try it before I die.
It would help if there was a mini-map, 'cuz mostly the whole map looks the same with no landmarks.
And it isn't fair that some enemies such as flamethrowers show up OUTSIDE the map where you can't get at them, IN THE WATER. How is that guy walking on water? Why does jezus want to kill my harmless innocent monster?
And the airstrikes targets show up and bomb so fast you can't really DO ANYTHING about them as a player.
