This is better than games that take years to make... Awesome job! I am a Synty enjoyer myself. Are you using a dithering shader and a static screen overlay here? I'd love to know how you got that effect.
We're using the auto smoothing in Unity as well as a smoothing shader. Then Beautify Unity addon for the screen space effects.
Yeah, I can model stuff like Synty, but for a 4 day jam it was better to put the focus somewhere else considering we already had the assets haha.
