I played about half through it and had to pause. Afte reloading my charecter does not move (jump still works). Is it possible you updatetd your build in last couple of days?
On what I could see:
Gameplay is engaging. Strong sense of exploring is present. Abilties are pretty standart, but it fits well with narrative and level design.
Movement is responsive, as is combat. Solid platformer. Enemies AI is.. Well, it is there :) Sometimes it was even good to pass by all fights in fast run to specific room.
Story... It may be really well written, but imo it is out of place for gamejam. I was feeling like skipping it, because I was eager to continue playing. Maybe in full game for several hours it would be nice change of pace, but in my 30 or so minutes run it felt like stumbling.
Overall great game. I really enjoyed it and I would like to finish it, if controls problems are not permanent.
Good luck!
