I enjoyed playing this. After trying them all, grasshopper was my bug of choice.
The betting organs idea is totally mental, but I love it. It somehow makes complete sense...
I don't really have any feedback on what I'd change, other than more of it! More organs? That might be weird... Maybe some kind of permanent upgrades to the bugs themselves? Maybe some kind of bug battle royals' with many bugs?
Really cool and innovative game, thanks for making it!
