I love games and math. I'm learning and having fun. I think making games should be as fun as playing them. I'll probably publish mostly unfinished prototypes and demos but I do have some ideas I want to develop fully.
I like peaceful games. I prefer games that don't have a defeat condition. Games that always reach their end, no matter how clumsily you play. Games where you can explore at depth or just run through without worrying about getting stuck of seeing an unexpected Game Over screen.
That said, I like a game that's challenging and rewards commitment and intention. Games where careless play reaches the game's conclusion but only purposeful and attentive play lead to top scores and completion.
I like random and procedurally generated stuff. Kaleidoscopic worlds that you can play a thousand times and still be surprised. Or games that people will play only once but each player will have a unique experience that nobody else played.
