The game was simple ! You have a raindrop and you click and drag it to the seed until it grow, the game loop is definitely there =), would've liked to see more level ! Also, i think maybe there's an issue with how you might've exported the game because on my side, with firefox, the play zone was small versus the screen ( see picture ) and some button didnt worked, like the option button on the main menu, then again, this might've been an error on my side. Maybe you can try to export the game to windows/linux/mac ? Also there wasn't any sound. Again, might be on my side.
