Pretty cool first go-around then :)
The raindrop-dragging script as well as making it look alive
Tips for improvement:
Player info
When the plant is done growing, it would be nice to get a “level won” popup as feedback to the player to move on. And ideally redirect to next level / main menu.
Resolution
As the other person said when exporting to web, you might encounter resolutions you weren’t expecting.
For the main menu, this means you could look in to scaling UI.
For in-game, it would possibly be repositioning the camera :) (or manually adding one to the scene)
Keep on Jammin’ ;)
