Really great twist on the scalable platformer with the swapping scales! I took a while to realise you could scale platforms, but after that I moved through puzzles pretty easily (despite dying a lot). I didn't entirely wrap my head around the maths of swapping the scale but managed experimenting my way through it anyway, and I found the speed mechanic really fun when I got to it. The final level was really exciting and probably my favourite level, though unfortunately I didn't finish it all (finally got past the first moving platform once and then realised there was more :'). The visuals also look really polished- great game, well done!
