Nice entry, with very cute art!
I managed to pass the first level, but maybe some feedback that some tasks are completed would be helpful, especially for more difficult to understand tasks like "Bunny kills a dinosaur" or "Bunny befriends a dinosaur". Also I don't know if I pressed the wrong button but each time I wanted to restart building the level all my objects from the previous tests were removed from the level. It seems more intuitive to keep the objects at the same emplacements.
I like how you managed to make a game engine into a game by placing objects in it. Solid entry overall, with a great introduction and gorgeous art!
