It's not new anymore, but I really like Micro Mages, a vertical scrolling platformer that fits fully into an original 40KB NES cart and supports 4 player simultaneous co-op.

Alwa’s Awakening got me pretty good.

I was really impressed and satisfied by Goodboy Galaxy, a GBA game recently released.

I've bought the physical Evercade edition and played on a Super Pocket for a nice retro experience.

Haven't played many recent homebrews, but of the recent-ish games I did play, other than Micro Mages mentioned in another comment, there's Nyx - The Paradox Relic (NES) and Tanglewood (Mega Drive).

I haven't played it yet but Mega Man Regenesis just released like a week ago

I recently started playing Pokemon Unbound; my starter just evolved for the first time, and I'm having a blast. I nearly choked laughing when I finally understood what was going on in the first gym, can't believe I didn't get it immediately.

If you like Pokemon, Unbound is an awesome game that has a lot of quality of life features + an original story! I also love that they let you choose between Beldum (Metagross), Larvitar (Tyranitar), and Gible (Garchomp) for your starter!

I am moving to Piefed at scallisto@retrofed.com (https://retrofed.com/u/scallisto)

https://earthiongame.com/ is fantastic if you liked Thunderforce!

Apotris is a super polished and customizable Tetris clone made for the GBA, though it also has native ports to desktops.

I really like D*fuzed as a nice GBC puzzle game with a charming little story mode

The other day one of my friends mentioned the SNES game The 7th Saga. We talked about how hard it was and despite all of us playing it back in the day, none of us ever beat it.

So, one thing leads to another and now we're in a race to see who can beat 7th Saga first. Most of us had old saves to pull from, so it's a shotgun start. I think I'm winning, but there's a long ways to go.
