Serious bugs. Developer needs to listen or it's broken. One of the best RTS of all time, ported basically onto android. Works on S21. graphics decent not high, no settings. Touch control is manageable but fussy, issues with unit selection/camera control and UI is very crowded. Options to turn off elements would have been good, but hey its a phone. Looking forward to seeing on a tablet. Don't believe expert setting will be playable with these controls vis rapid micro... BT mouse works with DEX
