This is a really well polished entry. The animations look great and the audio is awesome. It felt good to unlock the abilities and finally use them. It reminds me of the 2D zelda games with its top down style.
Some thoughts:
- Some of the areas feel too hazard filled. The ice area in particularly was frustrating at times to work through. The blue blob enemies are very spongy and multiply. There's also those tedious crystals which force you stand still while waiting for the animation to finish.
- I noticed that the character direction flips depending on the mouse. So you can move left while the character is looking right. It did seem a little odd. I wonder if maybe you could slow the player in that case to make it seem like they're moving backwards?
Overall, really awesome job!
