Great game! The platforming was deceptively challenging, but the fact that you could replenish and upgrade your hearts made up for it. I think the beginning was a little too difficult just cause collecting enough gems to buy a heart was a task that is likely to make you lose more hearts. (Maybe there could be more gems early on, or the price could start lower and go up as you play?)
Small gripes aside, it was super fun to play and the color palettes look amazing!
