Hi! Thank you so much for the compliments! They were really nice!
Unfortunately, the commands were designed without realizing that this would be a problem for the web! In fact, I made sure to also release a version that can be run on Windows. I think adding more keys is outside of Bugfixing, so we didn't do it. But if a cursor really does solve the problem, well, we'll keep that in mind! Maybe for a future time when we want to explore the game again!
Thank you again! Really! (Sorry for my terrible English, but it's not my primary language).
