figuring out source code from fan games

[cjl8336]

I found a fan game from 2017 programmed with ruby and decided to mess with the code -
I managed to activate debug mode, so I'm gonna test the whole game and see where I can improve it
It's a mariovania style game, think classic mario gameplay mixed with igarashi style Castlevania
I forgot where I found it but I can post the files if anyone wants to try it - it's not my game though, but perhaps if others are interested this game could certainly be expanded
I just lack the programming knowledge to add more to it...

I don't know ruby but that sounds fun. I wanna try it
