Just too good! you have done very impressive work. You should launch a collective aimed at producing high quality GBA games and keeping the console alive, because the anticipation and now playing has been amazing
can I suggest having the space outside the walls filled in with some sort of psychedelic/ghostly effect. similar to Hotline Miami but more to reinforce the era, the setting, and the physical and mental state of the character via abstract effects
lo-fi gothic country in the trailer, modern surrealist-adjacent (if you can pick my username you'll blow me brain away), beaut chip-tunes, ripper game play! you better make more platformers, mate. maybe a top down rpg even!
