itch.io

They mean the Itch.io desktop app

This is not a mac problem, I use bootcamp, which basically turns your mac into a windows PC. The only difference between a bootcamp mac and any other windows ultrabook is the keyboard.

And either way, I think that adding an extra "accessibility " feature might be a good thing even for non-bootcamp users, for example, someone might have a broken del key. Anyways, not doing this is sad, but I understand you. 

However, low-res fonts are clearly visible on your own screenshots. You might be using a 1080p display where they look OK, however, on 2K and 4K display they look quite bad. Also, I've noticed that it looks like it's not a font problem, but it's just that your program is simply rendered at a low resolution. Here is an example of this from your own demo video:

And just want to clarify one thing: I don't want to trash on your software, I just want to help you make it better for everyone.

I've noticed that the whole tool runs in really low resolution which is just scaled up. Again, I understand that making this fully scalable might be really difficult and time-consuming, so maybe just make few versions for the most common types of displays (SD, HD, 4K)?

And btw, how do you delete nodes? I suppose with a del key, but macbooks don't have it, so i can't check. Can you maybe add a backup solution like using backspace or ctrl+backspace? It will simplify the life of all the bootcamp users greatly, and mustn't be too hard to add. :)

I've checked th demo and it's awesome! However, the fonts look really bad, especially on 4k displays. I understend that sometimes fixing stuff like this might be a real pain in the ass, however, it will greatly improve the general look and feel of the tool, and will make it much easier to justify paying 10$ for this.

I can recommend checking out fonts like "Exo 2" (you can find it on fonts.google.com), but there are probably fonts that are better suited for this.
