Yup, simple grey box geometry is often used to get a good feel for how a game plays. Easy to make and you don’t feel bad if you have to throw it away. The idea of the game also sounds very cool. The example looks very smooth.
Yeah, I made it. Spent a lot of time tweaking all the lil values to make it *perfect* (at least for me lol). Got even smoother recently but I haven't shared an update yet 🙃
