Lets be honest… there is a LOT of stuff on the eshop and it seems dozens are added daily. A huge amount of trash to be sure but what gems did you stumble across in there? That you want everyone to know about because they are surprisingly good to awesome but you never see brought up on here?
My love is Kharon’s Crypt

An absolutely massive love letter to NES/GBC era Legend of Zelda programmed by one dude. Picked it up on a whim and 26 hours later Im still going deeper into it and being continuously surprised still.
You play a spirit that can be attacked and destroyed and has almost no interaction with the world BUT you can possess enemies to interact for you. Push a block? Possess something with hands. Big gap? Find something that flies. Fight till the body dies then hop into something else and keep swinging!
In true LoZ fashion (Metroidvania is a term but I think Zelda-Like is more accurate) you will solve an ever expanding variety of puzzles, collect more items and tools for yet more puzzles. Secret rooms everywhere. Bosses are big and tough as hell and there is just tons of lore and detail to just absolutely everything. Even the bombs have lore.
Built in achievement panel with some real interesting challenges and an unlockable hard mode that I havent touched yet but am sort if worried to do so.
Now the part I love but could turn some people off is the whole thing is styled like a GBC game. Better color pallete. Same screen ratio and limited buttin controls. I get what he was going for and love it but the intentionally archaic framing could bother some people I imagine.
