Thanks for playing and the comments. Cool that you managed to get out and thanks for sharing it took a few attempts. The enemy/monster spawn trigger is related to tile count and the 'hunt' behaviour again triggers based on either tile placed count or the existance of the exit (depending on difficulty level as well).
At the moment there is no way to deal with the enemy, but toyed with a combat mechanic and a fear of the light, but need a lot more time to work through the behaviour and logic.
I also had a mode that included the exit you needed to build towards, but the tile/shape and orientations sometimes caused that to be quite difficult to get to and often in testing, I overshot it and so couldn't quite get to it... that was more annoying that enjoyable so I backed out of that design choice rather than try to work through and solving it.
I did add/leave a few hidden keyboard controls (G) to generate a random dungeon and (Backspace) to spawn additional enemies. One of those helpful dev/debug features that I left in cheekily and tbh can make it pretty tough to escape.
I really enjoyed making this one and hope to find/make time to develop it further.
