Thank you. Still feels like and endless set of features to add: tournaments, hot keys, animations, etc.

It took about 2 weeks of nights/weekends to have something functional I could play with friends. The engine was the hardest part. Then another week to open to the public and then it’s been a few weeks of bug fixes before it started to feel pretty stable.

What about you?

Took me 2 months of spare time in total. Engine was definitely the hardest. Debugging was also tricky, due to multi-threading.

Agree. I wrote the engine in Node (so punted on the threading problem a bit) then just ported pieces of the engine to firebase functions to handle the actual computation. Made testing a bit easier as I could just simulate players client side. What did you build yours in?

Mine is aws lambda + redis. I rely on extensive testing to flush out bugs early. But sometimes I do question my initial choice :D
