5 stars: As far as piccross apps go, this one is the best I found. Simple UI, it fills X when necessary, which is helpful, and it is not infinite, and no annoying ads. I like it!
5 stars: This is a really well made puzzle game, completely free to play (the ads rarely appear outside of menus and don't distract from gameplay) and I love the nostalgia factor with sprites from old Konami games like Castlevania, Bomberman, Gradius, Pop 'n' Twinbee, Mystical Ninja and loads more! Definitely worth a download
3 stars: The game itself works well. But, you should be able to play through the boss battles after you have beaten the rest of the game. I've got 50 boss battles and three hours of waiting in between each battle. Which effectively means, I am done with the game. I'm not going to sit and wait. I like to be a completest, but it's not really worth it.
4 stars: Great, but I already know how to do nonograms. I don't really like that I have to do 5x5's before doing larger ones, which I am used to, but it makes progression fun.
5 stars: Super fun, and relatively challenging at times! I've done massive puzzles before, and these are still entertaining. It's nice to have quick puzzles to go through that aren't mind numbingly simple. Love the konami theme as well
5 stars: Really good free game! Includes some nice classic tunes and proper old school pixel graphics from a wide range of Konami retro games. Puzzles do become challenging after a while but all can be solved ...
