Well, I’m on my ROG Ally at the moment because of Game Pass, but I just finished up Cocoon. Can’t recommend it enough. If it has a story, I couldn’t tell you what it is, but as a puzzle game, it’s fantastic. I think it strikes that balance where you feel smart without it being frustrating. Portal does that too. This was my favorite puzzle game of the year, easily.
I tend to play on my AYN Odin Pro, but I also like my RG351V for certain games and my ROG Ally has VRR, which is neat for getting the weird refresh rates to match old consoles.
Tinykin - A platformer with a dash of Pikmin. Like, a very small dash. Some reviews way overplay the Pikmin aspect. It’s more of a collectathon platformer, and the Tinykin are more or less just abilities you need to collect in every level. There’s no strategy and you’re not at risk of losing them unnecessarily. There’s enough to collect everything in every level. I loved the game, but it’s not Pikmin.
Pokemon Luminescent Platinum - It’s a BDSP (specifically BD) mod that makes the games Platinum with some additional QoL stuff like a built in level cap so you don’t get overpowered, additional moves and Pokemon, and just a ton of stuff. It’s very good.
He also has great written guides on his website.
