Runs on all my devices, the game is as you would expect and although the UI works fine, no issues at all it isnt the best thing in the world to look at, could do with some help on that. Even the launcher icon and playstore png for example could do with improving IMO, so let me know if you want any help with that. Also, although I could solve the puzzles, the images used often were 'only just' related to the word to be found, don't know if English is your first language, and if not you've done a fantastic job but some bits of it seemed off somehow. Cant put my finger on it...
Overall though, as a game, it works fine on all I tried, the mechanics are all there just I personally think the looks can be improved, but that could just be me. If this is the first test to check it 'works' then it does, if version 2 of your plan is to improve the UI then I look forward to that, and again, any help with design ideas I'm more than willing to help. I cant code or develop for s**t, past compiling roms, so this is all I could offer
Good luck though all the same.
