For as long as I have played this game, I have NEVER liked boss fights. I feel this is a pretty common opinion to have, but I think I can still say with confidence that this level is the absolute epitome of why I feel this way. The gameplay is sincerely just so poorly made. It would be a god damn easy demon if it actually functioned correctly.

For the first part of the boss fight, the indicators for where to go and what do are pretty difficult to react to sometimes and lots of the inputs you DO actually have to do feel generally awkward. At the very least, it is possible to form a semi-consistent strategy for the part, which makes it at least tolerable when going for a completion. The same CANNOT be said for the second part of the boss fight, where most of the indicators actually just straight up lie to you. It would be at least somewhat better if you consistently had to click earlier or later than the indicators, but the timing differs for each one, so you genuinely just have to learn what to actually do for each indicator, which is AWFUL design when not indicated correctly as is what has happened here. And even then, sometimes, it's just incredibly hard to telegraph when to click, hold or release to avoid a laser beam and you'll die for what feels like no reason at all. It just feels so random. The robot part right before the second part of the boss fight has the same issues, but to a lesser extent. At least you can get consistent with that part.

Thankfully, it's not all bad. The ship and wave sections in between the first part of the boss and the robot are genuinely decent, and the overall decoration is actually pretty good and thematic. Unfortunately, it doesn't excuse how annoying, poorly executed and unfair most of the gameplay is. What a shame that the doom gauntlet ends with this.
