There was reasonable discussion around this around his release
but I think you bring up the relevant point (and it’s not balance, so to speak, supported by what you said re: “Ignore the fact that I won”).
I think what you’re reasonably trying to say is that it’s no fun being forced to sit back and watch while the AI plays – and this IS a point that the Devs have responded to in the past back when Goblins were being more annoying (although I was still a young account at the time, tbh).
I don’t have too much to add or weigh in, here – I’ve only had Gobtruffle loop a little bit annoyingly against me a couple of times. I can see what you’re saying, though – if he’s looping, it’s not a fun part of the game to be in (a very powerless and boring/annoying situation).
