Thanks for playing and streaming the game, and for all the detailed feedback! Really glad you enjoyed it, especially since it’s not your usual genre.
I’ll enable the PSX filter by default rather than make players answer a bunch of questions before they can start playing. The sound previews are a great suggestion too! I’ll also work on readability, making available upgrades clearer, and helping players find their way back to the center on dark floors.
Sorry about the freeze at the end — I’ll investigate the map zoom and fullscreen transition. Thanks for pointing it out and describing what happened!
