It's like if you played OG DOOM on a pc from the 1990's except you took large amounts of LSD and CRACK

It's fun for a bit but some flaws hold it back. I would rather not put yes or no on recommend cause I don't like downvoting indie games if I can help it.

The powerups only sit on the map for 3 seconds, not an overstatement, unless you are standing right on top of it when it drops it's going to disappear so 90% of them disappear without me being able to get them, especially far away I shoot someone and sprint to the powerup but its gone before it was physically possible to reach it.

You can really only carry 2 guns to be able to have a free hand to pick up things and reload, except that you can carry 3 guns if you don't want an open hand, so you are incentivized to carry 3 guns and have to constantly drop the third gun to be able to reload or loot anything, kind of obvious bad design IMO.

The enemy AI consists entirely of "walk straight toward you while firing their weapon at the same interval" I mean it works but it's the most barebones thing possible, don't expect anything else.

There's no VR interaction with anything at all in the world, no picking anything up except the ammo/food/powerups, not a big deal.
It's pretty short and levels are tiny, just 3-4 rooms with some enemies in them.

For like $10 I could see it being worth it maybe, but I just don't enjoy it and there's barely anything there.
Just play the demo and decide if you want that plus a couple more levels for $20. When you look at the value vs studio releases, these solo VR devs are really asking way too much $$. And they don't even have to pay a staff they get it all, and good for them they did the work, but it's not worth it to me. This is FPS Ancient Dungeon IMO with the same problems. I would refund it but I bought it months ago and it's way too late now even with 1.4hrs.
