I actually used to speedrun this. Something about it's weird physics and collision detection made it feel like a rollercoaster where all the tracks were covered in soap and grease, which made it hilarious to play for an hour a day for eight months.
I played for 2 hours, passed almost all the levels, got tired of it, didn’t go any further, the obstacles are certainly interesting, but only at first, then everything repeats itself and gets boring
