Futoshiki & Futoshiki Pro - Sell Project

Futoshiki is a type of puzzle game similar to Sudoku that is very popular in Japan, the UK and other countries. My app, simply titled Futoshiki, has held the number 1 spot on a Google Play search for Futoshiki for several years. It has over 35,000 installs. It is free, and there is a Pro version which sells for around 2 GBP, which has sold 514 copies for a revenue of £1.06K. Both versions are included in this sale. For most of its life it consistently held a 4.7+ user rating. Unfortunately, as it currently stands it does not work on Android versions 7.0+, which has led to some poor ratings and a seriously declining install base. I can update it to work on these Android versions with about half a day's worth of work, but have not had the time or desire to do that. That is why I am looking to sell the project- if someone is willing to buy it for a fair price, I will update it to work on recent devices before transferring over the project. I have never attempted to monetise the free version, and there is great scope to do so. There are no ads, and a fairly generous amount of puzzles are included in the free version. If I were to monetise it, I would likely suggest adding ads, reducing the amount of free puzzles, and possibly getting rid of the Pro version and replacing it with selling puzzle packs in the free version. It is built with Clickteam Multimedia Fusion 2.5, a low-code game development platform.
