Good news everyone: Brainmelter Deluxe is now free! As well, I've just patched it with a few quality of life updates:
Level borders are now unlit, thus making the level layout easier to read at a glance
The player look left/right idle animation has been removed, as this was making it difficult to tell which you way you were looking when standing still
Fix for extreme screenshake at higher frame rates
