Really glad to see this is still being updated, because I've thoroughly loved what's available here. Interesting that monster synergies aren't shown at the beginning of the game anymore.
Also worth noting that I'm almost at 100 runs (the vast majority of which were abandoned before a game over lmao) and I've only managed to find the elusive Chip ONCE. Even when I did I still didn't manage to even get it evolved at all. The search continues!
I've really enjoyed updating it as well :D
Are you playing on the download version? Theres a new update out 2 days ago. (synergies not appearing was a bug that was fixed, and Chip has entered the normal pool officially and will appear the same rate as everyone else now).
Edit hold up, Chip's spawn rate might only be normal in the Egg event but not the team select at the start, I'll need to investigate quick.
Double Edit: YOURE RIGHT HE WAS STILL EXLUDED FROM THE STARTING POOL OOPS, he was only added into eggs and the sense at the normal rate, putting out update right now
