smart contract - We had hard time with deploying ASTAR contract on testnet, but we were able to debug it. Some issues with NEON deployment, and reported this to the devrel on site, and ultimately got it fixed by uinsg a proper API URL.

gamification and tokenomics - we wanted to make the game engaging, so we added a) progress level - competition between two sides b) timer - pressure to finish c) prize coin/point allocation logic. Also considering the tokenomics - whether to limit or offer unlimited supply - we ultimately chose to not limi the supply of the fingercoins by naturally burning the coins users lose in the gameplay.
