But there is an error that won’t let me purchase the full app beyond level 9 ### 2/5 — Great games until you realise you’ve paid premium for nothing *2025-02-16, version 2.1.5* The games work very well and then after about 9 levels, you are invited to pay £5.99 as a one-off payment to unlock all future levels, and there are many of them. There are clearly glitches here as error messages appear, and it keeps asking you to pay £5.99. My money has been taken but the app has not delivered. Easy way to make money! Where is the incentive for the developer to correct these fixes? He’s getting his money without having to do any corrections. Wow. ### 2/5 — Waste of download *2024-12-08, version 2.1.5* Only lets you play 9 levels before making you pay. ### 2/5 — Was fun at first but… *2023-04-08* I only get NINE levels and I have to pay for the rest but I CAN’T can u pls make the rest of the levels FREE that’s NOT to MUCH to ask for right? but I REALLY love the game but just make the levels free and plus it’s a ONE time purchase anyway byeeeee P.S I don’t really learn anything ### 1/5 — Some problem happened *2022-05-07, version 2.1.4* Once I purchased the game , I can’t open it and also it’s not working anymore !
