Thanks for the compliments and suggestions!
We modeled the controls after the classic FPS style, but now that you mention it, that may not be how the crawlers of old (and new) play on PC. The last crawlers we played ourselves were on console with controllers, so that might be a bias and an oversight on our part! But, fixable with a control-style toggle in a future options screen.
Regarding your second suggestion, I am just happy we were able to keep your attention for 10 minutes ;) But something like a -50% modifier on the spawn rate of explored tiles should make backtracking less tedious.
And Piromaan did the level design, so he’ll be happy to hear you liked his classic Wizardry-tribute door maze.
