Definitely interaction hitboxes, or whatever the interaction mechanism is - needs a lot of work. The game is cute and so are the dancing flowers, you can definitely add more fantasy elements like https://www.friv.com/z/games/dorasmagicalgarden/game.html does if you want to go that way. The game seems interesting otherwise!
And yes I forgot to mention the cubes stretching like pulled spaghetti in the form 😅
Looking forward to updates in the game!
