Hey man!
I'm glad that tip helped you. I use draw.io a lot myself, so I was really speaking from personal experience there!
Good to see you got some progress as well... way to go! I've done something similar to a (very) short game that had Gohan turning Super Saiyan 2 and shooting a Kamehameha. It's a pretty awesome feature to have, although I wasn't able to implement it in my own main project.
I'm currently trying to cure myself from something I just found a name to, which is the world builder's disease.
A nasty disease indeed, and something that I've always been aflicted with... although never fully aware of it until recently. Beware not to fall to it as well!
In any case, best of luck to you and hopefully you'll have more updates for us soon (I'm dying for more of your story!) No pressure though! Hahahahah
Cheers!
