The Steam Next Fest demo of this bullet hell roguelike has big Risk of Rain energy, and some cool tricks of its own

gamesradar.com:

I'm ending a week packed with Steam Next Fest demos on a high note with Gatekeeper, a top-down bullet hell roguelike clearly inspired by Risk of Rain. Pick a character, drop into a medley of environments, and shoot dudes while hoovering up items until the number stops getting bigger. It's a familiar formula with a new perspective, and while there are some mechanical and artistic similarities to Risk of Rain and its sequel, Gatekeeper feels like it's found its own identity.

I went with the default character for the demo, partly because they have a built-in second life (which I haven't lost yet, thank you very much), and partly because the vanilla character is always the best way to gauge a new roguelike. My kit also includes a standard aim-and-shoot full auto gun, a fireball AoE, a ricochet shot, and a basic teleport-style dodge. Imagine if Risk of Rain's Commando and Huntress trained up a bullet hell protagonist and you're most of the way there. 

There's enough bullet magnetism to make abilities intuitive to land, but not so much that you can blindly chuck attacks into the crowd. Enemies range from slow-moving golems and sentient obelisks to homing droids, and kiting enemies around while picking off priority targets is key. I'll gun down stragglers while saving my big abilities for juicy crowds, triggering all the items I've amassed as I go. My favorites so far mirror some of my favorites in Risk of Rain: enemies dropping explosives on death, seeker projectiles triggered by attacking, applying burn to enemies, and so on. 

One thing I appreciate in Gatekeeper is that leveling up by collecting XP is also a really big deal. There's a bit of Vampire Survivors in the way you draft boosts to your HP, damage, regen, movement speed, and cooldown reduction, and these stats can in turn affect what items you prefer. You also upgrade your abilities as you go, increasing their AoE, adding effects like burn damage, and so on. You really get a sense that your whole kit is evolving
