Thanks a lot!
The fake animals is a great idea indeed. At first the fake fruit thing was part of the gameplay : if you stop moving, animals will think you're food and will try to eat you even if you're bigger. However, it didn't prove to be really useful with the kind of game it turned out to be, so i didn't even mention it in the tutorial. ^^'
The difficulty is my main regret with this game, especially for the strawberry, but yeah, the stamina bar being the main danger was on purpose, to avoid a "spammy" gameplay.
