If you defeat all ten enemy waves, You should be taken to a second stage involving a boss fight.
It is an unfortunate bug that using the execution messes with the enemy wave spawner and gets you stuck in the first room, so I advise against using it if you would like to see the second stage, haha.
Al in all, this was a weeklong jam game so there is not much else to it, but for our first unity project I think we did good :)
