Wow, I really like the use of the unreliable narrator, made for an interesting story! Things like the 'world record long jump' were really cool! I did stumble into an unfortunate bug tho, I was falling as I entered the room after the long jump, and clipped through the world, soft locking myself. The game was enough fun to replay, and I'm glad I did. One thing I'd consider is making some of the visuals clearer. Some holes killed you when you fell in and some took you to the next room. The purple bushes looked more like spikes, and it took a while to realise they were harmless. Not sure if that was part of the unreliable narrator thing, but there was also some purple bushes that you could fall through.
Overall the game was great, I loved the style of the game, from the graphics and music to the story. All a very cohesive and polished experience, I had fun playing it!
