Pretty decent for a demake of something unreleased. Nice gothic-ish chiptune music, though it does get a bit repetitive. Good controls and platforming. Hit detection for enemies though and jumping from the final bosses hands to the head is wonky at times.
Sometimes I kill an enemy five feet away from them while descending from a jump without touching them, LOL.
Really like the ambiance, tone and setting, and think this could make for a good, more fleshed out release (or re-release) if you ever decide to continue with this.
