This is a nice entry! Although a bit flawed, doing a 3d puzzle platformer in such a short amount of time is impressive enough so I am not complaining. The idea is nice, the graphic and art style is great (I am assuming you built all the assets? Doesn't seems to be premade but I am wrong), we've even got ourselves a little boss fight! This is pretty good if you ask me.
So down to the flaws. The thorn's insta-kill is so annoying, and the hitboxes doesn't help either. I have died too many times by slightly touching the thorn, and need to go through the level all over again, to the point of getting a bit frustrated. I would suggest adding a small damage counter to it so that the player can have a bit of leeway before getting killed by the thorns. The mushroom / berry bounces are also a bit too chaotic, that it's really hard to do platforming with these. Not sure what to do about this one, but some assistant that guides the player to the intended destination may work. The force touch is a bit out-of-place, it just feels underwhelming when comparing with fire and ice. It also doesn't help with the fact that, the first puzzle for it is just not fun, especially the pushable mushroom where it's quite difficult to hit it with the torch.
But anyway, this game is nice, and with a bit of fine tuning it would be quite enjoyable! Good job!
