This game has been really cool! Just got the flamethrower and double jump. I wish the map had a little help with navigating, but that's definitely a problem with my memory and it's very accurate to oldschool games. Thanks for the game!
Some feedback notes though, having just finished the sunken city:
-I think east and west may be switched in some of the notes? The cold area is mentioned as being on the west side but it's the top right area
-The map being right next to the short-range flamethrower is awkward to use. To select it, I would either have to move through, then re-equip a different weapon after I was done using the map or move all the way around the screen to keep my current equip.
-Bosses could stand to be a little more dangerous across the board, so far I haven't needed to use any special tactics or even learn their moves.
