Mysterious Mineshafts

A short Metroidvania with a classic Gameboy art style. I was intending to make it longer and more polished but got caught up with other things about halfway through the jam.

Use [A]/[D] to meve left/right, [Space] to jump and [LMB] to attack.

The initial pet upgrade gives you a companion which can be used as a platform, pickaxes increase damage, hard hats increase health and the trampoline turns the pet's back into a bouncepad.
