Played ca. 60 demos and these are the ones I actually liked.

>Good
Blood thief - Similar to Neon White but with a thief-like aesthetic
Metal Eden - Very polished doom 2016-esque shooter
Ascend to zero - Good music and interesting premise. The resource-management aspect to builds/ combat is cool too
Jupiter Hell Classic - DoomRL good
House of Necrosis - Surprisingly fun RE dungeon crawler
Outlawer - Ace Attorney like VN. A bit amateurish in part but still good

>Has potential
Era One
Ninja Gaiden Ragebound
Dead as Disco
Phase Zero
Glaciered
Holstin
Turbo Blast
Verho
Dragon March
Wizman's World
Quarantine Zone: The Last Check
Quartet
Aeromachina

Somewhat lackluster Next fest this time around.
If there are any recommendations left, I'd welcome them.
