I've played Noita (https://noitagame.com/) for quite a bit, and lately it clicked to me, that the core mechanics of the player and environment come from Liero. Though Noita is a single player rouge-lite, it has wands instead of guns, but environment is destructible, and explosions work the same.

It's much deeper, both in mechanics and in lore, it has actual levels with progressions, but I was curious why did I enjoy that game so much. Turns out, I spent a ton of time playing its predecessors with my friends :)
