That is a nice game with nice art, Congratulations for submitting to ProcJam and thanks for creating that game :)

Here is some points that will make your game better:

• Consider making the sun enemies blow on interval instead of player near, the reason for that is with the colors of background and small enemy size sometimes I spend awhile looking for the last enemy to be able to leave the room. Unless that is an intended experience, I suggest changing it.
• I would have loved to be able to use the dash but control on the make with any direction make me move between desktops which is a shame (consider having an alternative buttons)
• for the room floor try to make more of repeated patterns and collection instead of pure random type of tiles as it will the rooms more visually appealing. Maybe use perlin noise  (with very zoomed in so it doesn't change as fast) to generate that different floor tiles
• For the room layout, may be consider having loops, to reduce the walking around to traverse the whole dungeon

Sorry if any of my comments sounded harsh or anything :) Thanks again for creating the game :)
