The game has good mechanics and is generally well made, however I am finding a lot of lag with my 5th Gen iPad - The game will typically run flawlessly until an ad comes on screen, then it runs like Windows 95, such jerky horrid motion making the game virtually unplayable.
I know the option is there to pay for no ads, but I am not willing to pay for a game that is unplayable on the free version. If you want more buyers, you need to get them hooked in. It's fine to have the video ads come up between games, but not have adverts come up during the game that stop the playability.
I find this a lot with Ketchapp apps; the games are very simple but quite enjoyable until the in-game ads start kicking in, then it's lag galore. I am not sure if it is the ads that are the problem or the developers simply don't care about the performance of the product so do nothing to improve it. Thankfully at least this apps ads between games are not unskippable as they are in so many other apps that are made by this developer.
Apologies for rambling. I am enjoying the game but finding it very frustrating when it becomes unplayable becasue you want to advertise other games you are developing during my gameplay.
