Tacker hitting the bullseye. The current steam release pipeline is far from ideal and it's straight up missing like 80% of the available features. Considering that releasing a game sort of by default means "release it on steam" it should be a seamless and fleshed out process but it's neither seamless nor fleshed out. Greengrinds patches up at least some of that but should it really take a 3rd party addon for that?
Getting the micro:bit plugin is not exactly a tradeoff in my favor because I have never even heard of this thing before and I have no interest in it either. Don't get me wrong, it's cute and all and maybe it was like an afternoon project after a heavy bugfixing spree to get something easy out... but even then it's a questionable allocation of resources considering we've been told time and time again that these resources are in short supply.
I'd totally be down if Construct would stop new features for maybe a couple of months and double down on robustness of existing features in the meantime.
