One thing that I can see is missing from the editor (at least based on videos - really would love to buy beta and would pay that $38, but it seems that I won't get it right away so won't bother to give you my money right now) is a way to execute certain scripts on certain in-game events, such as when a screen loads, when certain object is created or on each frame. Adding support for that, IMO, would allow for more customization without messing with the base engine too much.
If it's planned or already there in one way or another, I apologize. As said I'd gladly buy what's already there, the recent build, and I really feel like the engine suffers from not having open early access phase, both financially and by missing on important feedback that could come from people who'd use it but wanted to first see a proof this can be done (in my case, videos of alpha/beta releases) before throwing any money.
