Thanks for trying it out! I made a setting under the options menu at the title screen for turning off the poisoning because I kept getting it when I was trying to debug other things. It's a 1/4 chance, but for whatever reason !Math.floor(Math.random() *4) likes to poison me.
I was digging the look of your game (definitely a Megaman thing going on there), but I couldn't get tagging to work. I saw the tip on your game page, but it didn't work for me for whatever reason.
