A Pico-8 game in the wild, nice! The game was very fun and has a cute art style, and you did a great job in a very limited time.
My only constructive feedback would be to change the sprites of the “hazardous” collectibles. The skull is alright (duh) but the banana really got me confused because you would associate a delicious fruit with something “positive”, not something that removes your HP. With the fast-paced gameplay in play, I kept grabbing bananas because I subconsciously thought they were “good” pickups.
Changing the sprites so that they reflect what they “do” better would be my suggestion like a banana PEEL instead of a full banana for example.
Overall, good job!
