(If anyone wants to compare notes, I'm using the mouse to control the game.) Getting stuck on walls did mess me up a couple times and can be frustrating for some, but I really love the concept and how intuitive it was to figure out how everything worked so far. Repetition of room layouts actually helped me make progress, since I already knew what to expect, but didn't make it too easy for there to be a challenge. It took me a bit to master the controls, but eventually I did get the hang of them. The enemy design made sense to me without there needing to be an explanation - ghosts only deal damage when visible, slimes crawl on walls but can always do damage, moving spikes disappear after the bat stops being able to hear them, and the thing that drips the toxic fluid hangs off of a ceiling. I also like the little progress trackers in the starting room - maybe it'd be even better if there were counters for how much stuff you'd done total as well, to make it feel a little more rewarding to replay? Otherwise, the game is an interesting idea, even if there's a couple bits that could be refined a little.
