The count up/down idea is simple but pretty nice once it starts moving. I liked the little mental switch it asks from the player, tho sometimes I had to stop and re-read what was happening. Still, it has a good puzzle feel.
Thank you so much playing I really appreciate, I'm glad you enjoyed the count up/down mechanic and the puzzle-like feel. You're right that it could be explained more clearly. I'll work on making the mechanic and instructions easier to understand in the next update.
