just downloaded, thanks for making this. Heads up that the first thing I did was create an integer node and hit f4 to duplicated it, and the program crashes. This is reproducible. Win 10.
The latest version is 404, not 224. Those bugs were fixed in the later version.
Something got screwed up in the versions on itch. The version that was posted was an older version. It definitely was 404 at some point - not sure how it got screwed up. But however it happened, I'm sure it's my fault.
You should be able to update from the internal update (Help/Check for Updates). If that doesn't work for some reason, just download it again. Latest should be up here now. Sorry for the inconvenience.
