Thank you! It makes us very happy that you like it! Controller support has been a much requested feature, but due to the game the way is coded (and the fact that we didn't design it with controller support from the very beginning) made it a little hard to implement it. That said, we may add it in the future. In fact, we ordered a controller online a few days ago to test features like this one.
Regarding the Switch release, thank you for the information about Ratalika! We will look them up to see if there's a chance of that happening!
