Based on feedback so far, the next step developments/features to add may include:

• A 'Daily Extreme' challenge with harder levels for expert players

• Further work on levels/difficulty process - making levels more consistent in difficulty

• Pause button (stop the clock!)

• Multiplayer/realtime tournament (play a friend online) - in development

• Integration with Algorand (Web3) for micropayments/reward mechanics

• A 'level designer' - allow people to design their own level and challenge their friends to complete (partially developed)

• Mobile app

Please feel free to add suggestions/feedback here! Thank you
