I can see how spamming space to chow down seems like a logical decision, but it isn't a fun decision. At the very least it should have been easier to eat smaller things.
The graphics were also interesting yet detract from the game. It looks good, but it's hard to tell what's what. I couldn't tell the bugs from the nest from the corpses.
It does remind me of EVO, but the "spam space" thing really sets it apart, changing the game from "difficult" to "tedious."
