Wow, thanks for the detailed feedback!
More enemy and die types were definitely in the initial design, although the point about showing the upcoming waves is a fantastic idea that we hadn't thought of. Did you adjust the order of your dice at any point or did that feel inconsequential?
Also, I'm confused about what you mean by exporting to web - could you not play it in browser?
Not exporting it to Linux/Mac was definitely just laziness/sleepiness on my part, especially with how easy it is to do in godot so no excuses there! Even uploading a windows build was a last second afterthought since I figured the browser version would be sufficient for the jam but then suddenly remembered that certain builds were having WebGL errors.
Thanks again for such a detailed response.
