Hey there, in response to a lot of people being unhappy with rpgmaker's limitations we've put up an alternate build that's using the same engine as the Linux and Mac ports.
This should alleviate at least some of the issues that people encountered, like not being able to take screenshots or the steam overlay not working.
Read the forum post for further information and instructions on how to try it out:
