Neat.
Loved the presentation, there's some strong visual language in the game; the gameplay is.. there, but falls a bit flat on account of lacking any kind of juice/pizazz. First two levels were solvable without engaging the core mechanic of transmuting yourself to "sun-resistant", which rendered the first "tutorial" level less effective than it could have been, and having to switch between looking at the center of the screen (where the main action is), bottom left (where the countdown for "effect active" is), and top right (where current health is) is the main pain point I'd seek to remedy.
But overall a very nice little entry, it's playable, it does what it sets out to do, and looks great while doing so :) Congrats!
