I love this game, the concept is perfect except there are two things that are quite annoying: frame/tick rate reduction after a couple minutes of gameplay, and it increases the longer I play. I have an iPhone 7 with iOS 11. I understand that the game might have been created this way, since the black arrow keeps moving and is unaffected by any rate reduction. But usually, it causes the game to not be saved because the auto save becomes slower, bringing me to my next point: my game not saving. Simple fix, just add a manual save. If you want to keep the auto save, great, or if you want to make it much better, amazing, but a manual save, I think, comparing to other flash-style (Kongregate) idle games, a manual save would fit the game. Now, manual saves without auto saves creates the possibility to try something out and spend money, and then simply not saving and regaining the spent money. This is totally up to you to decide for what you do, or maybe some other people may have a suggestion for this one. Thanks! Keeps up the updates!
