There are 3 types of chao Basic chao, sonic chao and a shadow chao Sonic chao at light lvl 15, spd lvl 15, strength lvl 15. Shadow chao at dark lv 15, spd lvl 15, strenght lvl 20. Click on treadmill to level up speed, and the workout bench for strenght. To level up dark or light click the character in the top right everytime you do, it will turn into sonic or shadow, if it is sonic click the chao for light lvls, if its shadow click the chao for dark lvls.
I love the chao gardens from sa1 and sa2 and i wanted to recreate that on scratch. If you have a question ask me in the comments below, i will answer any question. Also this is a completely mobile game, please ask for sprite permissions, they are original.
