1. If possible, Curly's dialogue should change once you get the Martini so that she sees that you now have a drink, but it's not good enough (unlike the Curly Brace, which you give).
2. Before I activated the Spirit boss fight, I decided to look around for any hidden goodies, and I ended up finding an invisible life capsule between two of the binary shelf things. (and according to what you said in Skype, it should be obtained after the fight, which is when it appears).

Kinda sucks that this can't be a slope of sorts, but you can only do so much with Cave Story.
4. Rave Fortress was kind of oof. It's pretty much required to have the Level 3 Sixbarreled Polar Star in that place if you want to actually kill things at a decent speed. You also needed a bit of health if you wanted to survive more than a few hits (which I ended up having since I'm a stickler for backtracking for upgrades, which in this case were previously inaccessible life capsules). The flying Gaudi were also a little annoying to deal with, since their new rainbow color scheme made it difficult to see when they were about to fire. Back to the backtracking thing, Rave Fortress was kind of backtracking heavy if you wanted all of its life capsules, which was worth it, I guess, but also a tad bit irritating. One last thing before getting to point 5: when I checked the Boombox's description, it didn't have anything changed. It'd probably be a good idea to do so, so it's not just a reskin of the Booster 0.8.

Debug Cat's a ghost! Also, the second part of the fight had a nice touch, with the falling blocks, though with them being blocks that could nearly halve my health in one hit, even after all the life capsule hunting that I did, it was a little tense.
6. Finally, the fight with Corrupted Debug Cat was a little oof as well. It took me a while to realize that the rips in the environment were essentially floating -10 spikes, which was kind of an error on my part. Although I didn't fall onto any of the -127 spikes during the Puu Black form, it would kind of suck to make a slight error and have to redo the Toroko+ and Igor forms again. Finally, for the Sisters form, I had a harder time that I think I should have with it, though it was probably an error on my part again, since I was trying to use the Sixbarreled Polar Star instead of something that fired faster, like the Level 2 Shoddy Lyrics. Overall, it was also kind of oof how so many things did 10 damage when at the time I had a maximum of 29 health.
