Thanks! I agree with both your critiques.
The first complaint will naturally happen on each run; the item pool uses a deck system (it will generate one of every possible orientation & type of circuit before reshuffling) which means it will be a ratio of (4 + 6):(4 + 1) = 10:5 circuits with 2 or less connections throughout. I probably should have just removed dead ends from the item pool. A rotater building also would have been cool to add.
I also played through your game, it’s my favourite game from the jam so far!
