You've outdone yourself. I probably played for 10 hours over the past couple days and beat the game several times. Now for some rambling feedback:
I did run into a few crashes. I don't know if any of the logs would be helpful. I saw this but didn't submit anything because the form itself seemed very buggy:

Not sure what the solution is, but I think the main reason is that earth is able to push things away from you so easily. You can kind of play the game by button mashing, while lightning forces you to be much more careful. I find the throne room very tough with lightning, but a joke with earthquakes.
I think you should try to improve the monster art either through getting an artist going again or doing it yourself. You're probably skeptical of the last option, but I bet you could come up with some decent pixel art if you gave it a shot. The main problem now is that the styles of the main character and monsters are just not similar. Just adding a near black outline would be a huge improvement:
You were thinking about commercializing a game last year. I think this is the one you should run with. When I finally figured out the mechanics, the game made me feel like a goddamn wizard.
One last thought. When I first played the game, I accidentally used only air abilities and stumbled upon the swapping scene. I now know this to be, though a nice touch, really just an obscure thing that can happen. But here's what I
thought the overarching story was:
-You play the game through as Air.
-In an ironic twist, you too become trapped while trying to rescue Earth.
-Now, Earth must try to rescue Air.
Looking back, that misconception of how the game was going to play out was really beautiful. For one, it has this brilliant symmetry where you are forced to play both characters. Not only that, but Earth is obviously much more challenging, which makes sense for your second run. The swapping part, where your character gets trapped, is poetic. Anyway, I just think that might be an interesting way direction to take the game. As is, you can't easily play both characters, which affects both the theme and the gameplay.
