Atziri Temple suggestion

Make path tiles rotatable

Battery rooms easier to place

Make every run give a room reward scaling with room level and wether battery rooms are connecting to them

Make special rooms give you a clue on how to power them to get their special reward

Allow free portals in and out an active run or be very explicit that a portal out ends the run

Also, maybe the most important one - Actually explain the mechanics somewhere. As of now its a waste of time with trial and error and no rewards.
