Not even 1 star

Each time kids accumulate 8000 microbots, it crashes, then will never open. Once delete and re download it will start from scratch again, then through same viscous cycle, I suggest this app either fixed or removed by App Store, and all clients money should be credited back, we bought it coz we trust App Store selectivity, and high standards before they list any app in their store
