That's a Heavy Iron game, all right. Collectible-locked doors, fonts, abusable collisions, and some sound effects are reminiscent of BfBB and TSSM. That was a pretty fun, glitchy watch. Hope to see a warps TAS sometime. Looks like it starts from preexisting save data. Do you have an input file that sets up the save for someone to play back your TAS? Good to see it syncs without SRAM.
