You've got a great start to a unique incremental game, I'm digging it. I think you got something, here!
The big draw of incremental games is "number go up". So the fact everything is unlabeled and that's the entire point is unique- I will encourage you to explore other "game juice" options to give some sort of feedback to the player. The reason incremental games work is because people like to see number go up.
Another incremental game I would encourage you to play is Gnorp Apologue. It's still technically number go up game (prestige requires you to do hit certain numbers per second), but there's other visuals that give the player satisfying feedback on progress.
