Very good game idea. The module upgrade system is what makes me want to play more. Here are my suggestions:
- In the module crafting page, let players know they have to press Z again to close the page.
- html5 version is too big for my screen, there's already a full screen option so it's alright if you make it smaller.
- There's also a bug when picking gem, I picked it but it won't go away so I could not continue on that run.
