Hey, nice work! I unfortunately have no way of playing the level, but I gathered some points from your playthrough:
- The individual parts of the level are nicely varied; each room felt fresh and interesting.
- The room with enemies on top of the blocks (1:30 in the video) stood out to me the most, as it requires the player to change up their pace and playstyle a bit; I would recommend you to focus on 'twists' like these which will make the play experience more varied.
- Lastly, the only criticism I have is in connection to backtracking. Since you require the player to backtrack, I would recommend adding something new on the way back (e.g., new traps, new enemies, slight changes to the rooms); a simpler solution would be to just allow them to teleport back to the main crossroad room, but changing up the rooms at least a bit would definitely be more interesting.
Hope this helps and feel free to reach out if you want me to elaborate on anything!
