not sure if dev team is checking comments on itch.
their discord might be better option for bug report&feature request.
(I don't have a discord account tho, so cannot really tell this will work but you can give it a try.)

Yeah, I was afraid of that. I have anxiety about discord rn. Haven’t logged in on a few months and I probably have 10,000 messages to read. 😅
I’ll see about logging in there soon to double post this request / bug report. In the meanwhile I wrote a pretty crude glovepie script to use the number pad to place blocks, and the number keys to select them. It’s not great and it breaks for boss fights because the grid moves slightly, but it’s a stop gap for now.
