Managed to save them all as well. 😎 I think you could have integrated the theme better by having more of them, so the player would have to carefully choose which one to save, adding some replayability as well!
The graphics are lovely, just a tiny bit of bloom would make it perfect (Yes, I love bloom if you havn't figured by now 😂), the sounds are also good and the background music fits with the cozy puzzle game.
I also think you should add gravity, to add some depth to the charge and launch mechanic (because charging is kind of useless right now).
A shame it's so short, the idea is cool!
