Hi! I'm friends with the demake's developer and with his help I put together a version of the demake with the cutscene length reduced to 1-2 seconds each (can't be any shorter due to how the cutscenes are programmed). It makes for a much smoother speedrun thanks to not having to wait for a full minute 30 seconds into each run. Was thinking that this is the one that'd be best for speedrun timing going forward.
