Gun Princess Zero is difficult to play with a German keyboard because of the X and Z keys. The game is somewhat imprecise when shooting. I find it nonsense that I can collect coins when I jump up to another level. Sometimes I only need to jump up 100 times and then I have 400 coins more. But the game is not bad. For me, it's the most interesting game from the provider, some older games don't work properly for me, newer games like ZOwO Keeper (14.11.2019) don't work for me at all.
