Very fun and pretty game. I find the movement very fun and I liked the challenge of the final segment but its a huge difficulty spike from the rest of the game. The 8 and a 0 in the font look really similar so it took me a while to figure out what the numbers meant. I feel like you should be able to normally jump if you're standing on the ground and the red ghost should trigger if you press jump while in the air kinda like a double jump.
Are you planning to work on the game after the jam? I would love to see more levels for this.
