Yes actually I added some stuff, including some "donut" shaped tunnel sections so you can go either left or right at certain points (although end up at the same spot either way), the plan is to perhaps add a blockage or hazard in one of the two direction for those sections.
Also most significantly I added a boss fight after round 4.. Its a large sphere shaped room with a boss spaceship patrolling around that engages you once you make LOS. The mechanics are fairly simply but involves a reflective shield that needs to be taken down before you can damage the boss.
Ill make a video and add it to the thread, meanwhile I already updated the ZIP file and edited the first post to include the changes and spoiler info on beating the boss.
