I will be sad to see this go. Playing this casually (a couple days every couple months) I have become quite comfortable reading Hiragana, and am getting better at Katakana. I spent a lot of time on Duolingo and other sites, but none really got me comfortable with the alphabet until this game. So thank you so much for making this and sharing it!
It's 2020 and this game is still great! I found it not too long ago, and have since learned all Hiragana and almost half of the Katakana. I have been using lots of other apps/websites (such as Duolingo, Tinycards, Learn Japanese to Survive...) but for me this has worked much better than anything else! And it's fun.
