On 1st quick test prior to game sound being added, it played fine on a slower Intel GPU. Had to use Alt F4 to quit game, then it restarted. See fast walking (run) is made possible by the shift key. NICE game for sure! :) Newer version (61MB's) with fun audio works well. Once you quit it, by design, it "seemingly won't" let you replay beyond opening screen; only option seems is Quit... in keeping with the Jam theme, Delay the Inevitable.
