I really enjoyed Pixel Puzzles: Japan and UndeadZ. Is there any chance that another Puzzzle game is coming to steam soon?

I love your games. I have Pixel Puzzles: Japan (100% achievements), The Culling Of The Cows (100% achievements), RADical ROACH Deluxe Edition ( hasn't any achievements) and now I'm trying to do 100% of Pixel Puzzles: UndeadZ, but there is a simple problem: Kill 5000 Menu Zoms is insane without take a break. It's very easy for you to put a simple button to stop the game. Thank you! ...

I have to admit, I wasn't expecting these sorts of achievements when I bought the game, but I still feel committed to 100%ing it. Can this achievement be spaced out over multiple attempts? I already have the achievement for surviving 60 minutes in the main menu, but my brain couldn't take another 40 minutes of that, so I quit soon after. Will I have to kill all 5,000 in one go, or should I only expect to have to kill 2,000 more?...

After the last update it is still not possible to make a screenshot (F12) in the game. Can you please fix it with the next update?

I just solved Puzzle 7 two times. One with zombies and the other without. But I'm not getting the achievement. What I happening?
