This was wonderful! Absolutely thrilled to see assets being used, and love how you've expanded on the original hotel with entire new areas and new challenges (the platforming section in the sub-basement was fiendishly tricky - love it!)
Your additions to the art fit in perfectly, with the phone to save progress being a lovely touch that reminded me of classic Resident Evil
My childhood self would have been delighted to see something I made being used in an actual Gameboy game - thanks!
