For the easter rabbit idea, it costs 300 power cells/batteries, and when clicked on when locked, it will say collect 300 Power Cells to unlock this egg-citing lagomorph! When clicked on unlocked, it will say," An egg for you, and you, and you!" I feel like the design should be stripes and zig-zags with the colors of blue, pink, green, and white dots around it. Can you also make the design (if you will) carry an easter basket, and when you play, all the power cells go into your basket, but when your basket is full, it will look like it has 5 power cells in it.
I feel like there should be a costume for the bunny called the "Easter Rabbit," and the easter rabbit is faster and has higher jump, but the only setback I would suggest is less jump length and better manuverability. If you see this, I LOVE your games, I've been playing them since childhood and LOVE seeing your games evolve. Have a great day!
