Nice entry, some original mechanics, some issues, but really cool visuals and music.
i'd say my 2 main issues were, the level design and enemy placement, as some jumps are quite hard to make, and the enemies placed on some spots where you don't have that much room to fight can get a bit tricky, especially in the areas where you put a bunch aligned vertically on some cliffs, and since you cant jump through to jump up you gotta manoeuvre around the cliff and then get shot imideately by the guy standing there with little time to react.
That said it's still fun and i like the ideas you had, like that combat system of taking down the enemy's hp with one type of shot and once they are locked down you finish them with the other shot type, tricky to do but once i got the hang of it it was nice.
Overall well done especially since it's solo work :)
