Why do not Pokemon Deerling have 4 forms? Spring Form, Summer Form, Autumn Form and Winter Form 
I have 1 comment: Code it by month (every 3 months code a form) 
*January to March: Spring Form 
* April - June: Summer Form 
* July to September: Autumn Form 
* October to December: Winter Form 
As such, the game will not be heavy ... or slow ... because after 3 months you just replace the old code with the new code, the game will become more diverse ... more fun :Light:  :Light:
