I was a little skeptical when I saw this on itch.io's YouTube but playing it myself, you really got this thing of "conscious movement" down, probably the best possible emulation of that gameplay mechanic in a 2D game!
This is great for a jam game but I think there's even more potential here. I imagine the game boy environment lends itself well for other aspects of DS. Not the cinematic stuff and extensive lore, and definitely not the online aspect either, but the rest of it: Travelling from A to B. Hiking, all by yourself through varying environments, all with their own mood. Stopping for little highlights on the way, no matter if it's a hot spring that replenishes your stamina or just something interesting to look at. Delivering cargo and feeling the satisfaction of taking it from one point to the other, potentially even with little story tidbits around it to make it all more real. And of course, clocking it all in in Private Rooms.
I'm saying the game boy would work for this because imagining myself playing a game like this on a game boy on a rainy autumn day feels really cozy and melancholic. I think that it would make for a great experience.
So if you ever feel even slightly compelled to come back to this, remove the Death-Stranding-label from it and flesh it out to make it your own thing, even more than it already is? Godspeed, you got my blessings and I'd totally be here for it!
