When I play しりとり or しりとり cat, there would be suggestions about possible words. I think that maybe users would take advantage of this, using words not from their brain’s dictionary. So I’ve come out with an idea: what if there is a custom keyboard made by Renshuu, without giving hints of possible words?
It's all learning though, right? Isn't the point to improve your vocabulary, reading and spelling? Why would there need to be "a level playing field" in this case?
Keyboards are REALLY difficult to design - I don't think that, given my time constraints, working on even a partial "keyboard" would be helpful in the long run for renshuu.
