this is realy nice game but 1)The speed meter could be useful 2)Needs achievements 3)More shop that will let u customize your critter which gives your critter little bonus and spend money on upgrades that will give you even more money from bats killed. 5/5 :)
We do not think is easy enough to add it in this version, but it will be in the sequel. I've noticed that many players want it will be harder.
