Not Bad but some improvement is needed.
I enjoy the overall vibe. Loved the changing wallpaper in your cell. Feels oldschool. Its a breath of fresh air of all the repetetive .io clones we see nowdays.
Levels are a bit too repetetive. Maybe add some platforms or the gap between boseses should be 5 levels - right now is a tad boring between each 10 levels. Im not sure if the medals worked - might be prudent to double check.
Overall solid game man. Loved the idea. Keep at it!
