Hi Rocklead, that's good news that it's working. For now there's a lag when adding/removing blocks because the whole area reloads. I'll improve this but it's not high priority yet unless it makes the game unplayable.
Crashes are never normal and I'm continuing to fix those issues. I'll post an update in a few days and we'll see if the crashes go away.
Thank you for being patient with this, and I'll figure out a bonus/perk for the help you've been giving with debugging. I'm working on a demo for another 4d game that will be bundled with Moenablocks, when I publish I'll give you access to claim a copy.
