2 things that make a HUGE difference to my #gamedev / #indiedev motivation:
1. People actually playing the game! Nothing tops this. Someone enjoying it enough to play more than once? 🤯 UHMAYZING!
2. Constructive + positive reviews. Motivation often comes from reviews where the player points out specific things. Sometimes, they are things I never even thought of. Positive reviews boost my ego, which is motivational in its own way.
What keeps your motivation up?
