Nice progress, Mortusnyte.
I tried to do the same back when Epic just released the 2D Implementation as Experimental and it had a couple of issues, so that I couldn’t get that far at all.
IMO, a Super Metroid Remake or Fan Project with UE4 would be really cool. The only Metroid game after Super Metroid, which I enjoyed so far, was Metroid: Other M. Haven’t had the chance to play any of the handheld device Metroid Games so far.
