From the creator’s post · ilikedrpeppah on Reddit
i made this game with Opus and ThreeJS over 3 days i've watched jacksepticeye play SUPERHOT back in the day and played it myself and found the concept really cool. the art was rather simplistic but worked really well, so i've tried to create something similar with Claude to see what it has got... i've also added diving and time stopping to the core game mechanics, as well as a "match the beat" feature that encourages the player to move more methodically the level design needs work, as well as some other things, but other than that, feel free to share your thoughts or criticism or whatever else :)
