It's amazing how close this is to the arcade. Similar to the Genesis/MD version of Ghouls 'n Ghosts, playing this *feels* exactly like the arcade.
I noticed a bug with the blue acid blobs, where sometimes when you kill them, they don't disappear - they keep moving around even though they can no longer hurt you.
Also, the Home menu is a little wonky: pushing up or down moves between Play and Boss Rush as expected, but to get to Options you need to push left or right
Any interest in adding SRAM for saving high scores?
