Hello,
Dungeon Ball is my first project in Unity, released on Google Play: https://play.google.com/store/apps/details?id=com.karasgamestudios.dungeonball
You control a ball - a special one. Up to 8 energy sensors are activated on your ball upon collecting magic sources from the chests. Magic energies show on your ball and are then required to unlock each locked gate.
Latest update has leaderboards. Once you are familiar with the levels, you can compete in global leaderboard for each level. (You have to accept google play popup, so you level time can be shared in global leaderboard)
Thanks for your feedback and ideas!
