I have beef with greg. I dont know if there's any ankle breaking logic implemented in the basic enemies but I got cooked by a single one of them. More seriously this is a pretty good game, it's a good base to add even more types of weapon / enemy projectiles etc. One thing that could be better would be the upgrades, as cool as gregonance goes, I was disappointed when they were only in the range of 0.01% damage upgrade. It's too little to be exciting especially when you intend to conquer the greg verse. However that very could be a balancing decision. All in all really cool game!
