Kinakuta
I use a split keyboard and trackball at work, and I thoroughly enjoy the bafflement of my coworkers when they try to use my computer.
Probably a toss up between Hi-Fi Rush, Doom Eternal, and Guilty Gear Strive. I suck at fighting games, but I love learning all the unique mechanics of the characters.
I’ve been playing a lot of Cult Of The Lamb. It gets a bit grindy, but otherwise I love it. Alternating between crusading and base-building is a satisfying gameplay loop.
I can’t remember what the enemies are actually called, but the zombie dudes and the army dudes are the ones I always glory kill for health. I usually try to whittle them down with the rifle so I don’t accidently kill them before they go all flashy. Other than that, I just try to keep moving around the map, and review the codex entry for each enemy type so I know which weapon is best against them.
Have fun! I love this game.
