Hello, sorry for the late response. Glad you are/were having fun!
Resolution options are just monitor-supported resolutions in 16:9 ratio and perhaps that was naive of me. Like a 16:10 laptop probably has nothing valid there. I'll see if there is something easy I can do, like a launch option to just list everything or let you scale the window manually.
Yeah, there is a limit to the amount of summons. I have added a tooltip in the update that will clarify that before you find out the hard way.
