V's Rage is a hand-drawn arcade adventure inspired by the great arcade classics of the '80s and '90s that has no single genre.
The developers just recently announced that for the September 2nd release that the "Steam Deck, Linux and MacOS versions are finally ready for launch". Nice to see even more games are actually being tested and supported on Linux platforms directly. This one looks completely nuts too.

MANY GENRES. ZERO MERCY.
V’s Rage is a hand-drawn arcade adventure inspired by the great arcade classics of the ’80s and ’90s.
Expect frantic combat, absurd enemies, and gameplay rules that change with every stage. Each level throws you into a new experience: Beat ’em up, Shoot ’em up, Run and Gun, Side-scroller.
Learn, fail, swear, repeat. No tutorials, no guidance. Just pure, classic arcade
BETWEEN ARCADE CABINETS AND ’80s ANIME
V’s Rage is rooted in the spirit of old-school coin-ops like Final Fight, Altered Beast, and Parodius.
Its visual style is a hand-drawn explosion of ’80s anime energy, a nostalgic tribute to iconic characters like Lum and Ranma.
