Here's a few.
This one has the most creative movement in a platformer that I've ever seen: Rate Heart's Dive: A Snail Tale by iLazer for Brackeys Game Jam 2023.2 - itch.io
This one has incredibly good pixel art along with a great gameplay loop: Rate Deep Sea Dive by KenboDev, LeBebis for Brackeys Game Jam 2023.2 - itch.io
I'm pretty sure the devs of the following two plan on expanding their games after the jam, so any support and feedback now would be very useful: Rate The Gorge by Distru121, Cragi-Sandro4316, Ale_Ciao, TornadoEv for Brackeys Game Jam 2023.2 - itch.io
Rate Deepest Dreams by Valber's Games, Onilaf for Brackeys Game Jam 2023.2 - itch.io
This one's a tad buggy, but revolves around a great concept and is criminally underrated: Rate Sands of Avarice by error13660 for Brackeys Game Jam 2023.2 - itch.io
This one I completely forgot was a jam entry for a while and only remembered to rank it after I had 100% completed (tl;dr, it's good): Rate Scuba Steve's Salvage Squad by SAWD Games, TheHibiscusPoet for Brackeys Game Jam 2023.2 - itch.io
