Nice!

Are there any advantages in comparison to using DosBox?

@pavlor
It brings all the benefits of the "Omnispeak" engine to "Commander Keen" that were not there in the original game. A list of advantages can be found on the engine's documentation page:

In addition to the technical advantages, there were also users who used the engine to release their own fan-made "Commander Keen" titles.
