i would nominatate Card Delver and Red Line but i still haven’t finished them haha. Robot survival I a bit too rough around the edges (which is why im working on the sequel) so thats a no for me.
I would probably go for Hebes! by @InvalidProject since it’s art, story, replayability, gameplay, length and popularity is so high. It does need some bugfixing for the final boss though.
Games like Magnate, by @Octodemon, Layer 6 by @CreativeUsername and Kentonia Isles by @ADM_F (idk if ADM would be fine with us continuing the game tho) are also really amazing contenders for being super unique and polished. However these are pretty unfinished. Maybe we could release a demo for free on itch instead of steam.
Woofwoofs Unnamed Rhythm Game is also amazing but maybe loses a bit of it’s charm out of makecode.
