So, before heading to bed, my little auto-dragger script made it to the cosmic toast w/ cosmic blue cheese, jam & meteor ham. Sensing a pattern, I really hope there is no third stage of toast x)
Overall a quite fun, simple mechanic. For the later stages, the game itself chould maybe somehow switch gears, in order to limit the amount of toasts on screen, as they impact the input latency.
Be careful with the "downgrades", some toasts combine to the same amount of currency gain, effectively punishing the player by halving his income.
