Memory - Match Pairs Card Game 4+

This game is OK, and is what you expect in terms of selecting cards to match pairs. There are 5 topics to choose from and the images are good quality, with three ranges of difficulty - basically being the number of cards to select from. Hopefully the number of topics will increase in time.
However, there are a few problems.
After level 9, you hit next level and nothing happens, at any level of difficulty. You effectively have to close the game down and re-open.
There is no home button anywhere to get you back to the start. So same issue, you want to change difficulty or topic, you have to close down. When you come back however, you start again from level 1.
Pause the game, or stop playing, when you come back to the game you are back at level 1. It doesn’t save any progress, through any level of difficulty.

These are pretty serious issues that need resolving.
The needs to be a home button.
Progress needs to be able to be saved if so chosen.
There needs to be more than 9 levels in any topic or it’s going to get very boring very quickly.
There needs to be more than 5 topics.

This would be useful for helping those with impairments. It’s one of the simplest and clearest to use for that because the visual feedback is good and menu system is very clear.
However, it is let down by the adverts because to try to get some impaired users to learn to navigate past adverts that need different types of taps specific to the advertiser makes it a total no go.
And unfortunately, there’s no paid version that is ad free.
