It looks really hard. As a star run I think it could be fun, but as is it looks like a specific tight jumping thingy that's super tough without tools.
Also one of the rules explicitly states you cant use a level you made for something else, and if this is just lifted from your hack then idk if you can submit it. I mean even if it is allowed, it still looks too hard to be judged fairly. Keep in mind that anything that favours/requires tools to beat wont be very fun to play for most people, if I were you I'd either make it easier or just drop it altogether.
But that's just my opinion.
I think you should consider remaking your level with something less harder and not copy-pasting from a level you already made from your hack. Heck, you even put the player GFX together. In the current state there's a high chance of a disqualification for the difficulty and for basing from your hack.
