very nice puzzler with some good level design. I really enjoyed playing it and discovering new mechanics.
I wanted to finish it but I got stuck in this level. (now I write that and I guess I have to burn the first spikes, is that right?)
I also got stuck in that level, I think you need to go diagonal to avoid the first spike then go to the second spike and then you can go for the clear path, but I'm not 100% sure
You have to go diagonal on the spikes near the hole and at the end you have to burn ice to get the key.
It's a bit of at troll level tbh.
Oh, and there's a youtube video on my itch.io page which showcases each level and what is the intended solution.
Aaaaah yeah it make sense. :D
