Cool! Great presentation, and the gameplay is simple and satisfying.
Not sure if there’s just no ending, or if it bugged out here, but when the ogre’s HP hit zero, he ended up floating, and nothing really changed:

That was my second attempt, the first ended tragically early :)
My HP was near zero when he had about a third left, and at that point I switched to a much more conservative strategy: Keep running, and fire the E-Missile as soon as it charges. That got really grindy but it did work, he didn’t hit me at all during that time.
Difficulty, I’d say is appropriate for a game jam, but in a real game you’d want to go a bit harder.
