Congrats on completing the jam! I thought it was a great take on the theme! A shorter cooldown on being able to move your mushroom would be a welcome change, I found myself trapped and waiting out the countdown several times.
Congrats to you too! When I playtest, I usually turn myself back to a shroom when I see a predator (cockroach or mosquito) nearby, or when I need to avoid one that doesn't eat shrooms. I found that 10s is the sweet spot between being too slow or overpowered.
