Haven't managed to complete the whole game yet, but I liked what was there so far. It uses the RTP assets well and the original sprites are a nice touch. The biggest issue on this front is that it needed a more cohesive 'art style', but it was alright overall.
Looking forward to what you make next and I hope you'll decide to participate again in one of these jams sometime in the future!
SPOILERS:
The part I got stuck on was just after escaping from horse mask lady. I found a Glass Shard at the toilets, but didn't really find out what to do with it during casual wandering. I might come back to it later.
