this was pretty good! it's very functional in a lot of great ways like how you respawn really close to where you die and the heat meter. the screen size is a problem as others have mentioned, but the biggest problem is the amount of pointless space in a lot of areas. i like that you have multiple area types, but because the tileset in each area is very limited the shape of the room is how you remember where you're going and most of the rooms are laid out in a very similar way with lots of loops leading to nothing. one thing i learned during this jam is to think of each room in terms of what it offers to the player, like is it new visuals, a new item, teaching a new item, teaching the basics etc. thinking of rooms in terms of function i think would really mitigate a lot of the level layout problems. i still think it's cool though and a great one for your first try at it especially.
