GamerJC21 has produced a few good levels starting with The Gate of Fourkey. It has 5 realms accessible from a world map and each realm has multiple zones. Despite this set-up the game is entirely linear with very little backtracking. Being an early level of JC’s the visuals are on the sparse side. Though random-behavior type enemies make the difficulty unpredictable, it successfully ramps as you progress. Overall it’s a good play. Sadly, loads of stolen music prevent me from sharing copies.
