I found really annoying the autocorrect feature, since sometimes I accidentally mark a square where I want a cross. Please fix this! And besides I'd like to go directly to the medium levels. I love these puzzles, but it is boring to do the first levels, which are pretty easy. Great job though, congratulations!
Great game, I loved it! It would be great if it lasted for longer, and maybe a survival mode, I wanted to keep on playing when I finished it! But still, congratulations, great job
