I somehow by the grace of god found the portal on the 7th run. And that's after I managed to escape the void by swapping gravity twice.
I'm not sure how to rate this game. It looks pretty damn slick. But the gameplay is pretty stale, and I don't see how this fits the theme at all. I do always appreciate randomly generated games though, and I believe this is entirely procedural? So props on getting that to work proper. The amount of dead ends got me sweating though.
I imagine with perhaps another mechanic or two added this could end up as a pretty great full game.
