"Flow State in 3D"
Risk of Rain has an excellent core loop of killing enemies, opening loot chests, challenging bosses, and zipping to a new map in pursuit of the final challenge. The slower you go, the stronger the final boss gets, so hop to it!
While the mechanics and gameplay are all worthy of a purchase on their own, the way every upgrade you collect is physically attached to your character model is just exquisite. Chef’s kiss, perfection. Hits the absolute maximum dopamine of highrolling a build that does everything you wanted, then resets you to go try for it again or perhaps chase down some challenges or secrets in the various maps. The game is content-rich and addictive, then you layer online co-op on top to drag your friends in for an hour ish on a run.
I have 8 hours on Steam and ~30 on PS4 (latter is not explicitly tracked), ergo the sum time is greater than what’s listed on Steam.
