This has a LOT of potential, but it is barely a game in its current state; almost no way of interacting with the world, only 3 enemies and just a single looping animation that lasts about 4 seconds. Also, a bug sometimes causes the ghost girls to become invincible.
Will be watching it regardless, since I love this kind of boomer shooter-esque aesthetic.
Also, he's posted a new demo build on Patreon:

; might be a good idea to add it to the OP. It's even buggier than the original version and has some irritating music in the background, but it DOES feature a new environment, a new animation loop and what I think is a new enemy (a slime woman - never saw her in the original). No animation for her either, though.
EDIT: Yep, the Slime woman is present in the original. Still, the above build has new content, so I'd say it is still interesting.
