Thanks! I'm glad you liked it. ^^
The cherry on the top was the spell casting system...
I've been prototyping a "Space Shmup" recently with Medieval theme and Elemental Characters as ships and my head couldn't let it go of that idea...
And since it mixed perfectly with the theme Colors, I had to try it... It was great to had to limit the design to only 3 elements since time constraints and I think it worked very well.
The best part was I already was testing bullet patterns and that made very simple to make the patterns for enemies and bosses.
You are right about the Health... There is no way to regain it.
There was no time to implement a better progression system, this is why the "dungeons" are kind of a "Go as far as you can, die and repeat"
Thinking now... I should have put a High Score system for the farthest room you reached.
