If you know what you're doing, this could be your go to app for playing things like Brutal Doom on the go. Pretty satisfying for myself to have the ability to play with a lot on content that's out there. It won't play everything, but learn what to look for and anyone can still have a blast.
Would love to see more buttons listed for controller use. Missing toggle crouch and a button to pull up the menu, but has 6 buttons you can customize in-game for mods. This doesn't work for the menu however, since it isn't listed in either control configs. One glaring issue, which can be worked around via editing a .ini file. More effort than should be required for it imo, but still awesome with how the end result works!
