This game is neat with the exploration. But I think for each gold you collected that the player had to go back to the temple waiting 4 years each kind of putting time jumping bit too far for collecting each gold is bit too excessive for the game's plot. I think you could have put down 4 days later after collecting each gold so that the player doesn't wait every 4 years jump to make each time jumps too much. Maybe have all the gold collected will be jumping to a single 4 years instead of collecting every gold that causes the player to wait 4 years later too much. Imaging if the player had to grow very old when collecting all the pieces while waiting 4 years each after collecting one by one. That be too much time skipping. Also, you should add some music and sound effects in the game.
