This is super cool, i do find the landing areas to be quite unforgiving sometimes and I've only gotten half way so far, but other than that this is very solid! The music is really nice also :)
Yeah, after all this comment I starting to realize now, I was trying to be so logical so I made collider only on the surface . But game shouldn't be so precisely logical sometimes that is the lesson I learnt. And thank for noticing the music, you have good music taste xD.
Makes sense, you don't realise these things until you get other people to playtest it, i guess thats something game jams are very useful for! i'll try and beat it at somepoint when i have the time :>
