I'm just going to come out and say that this game is a marked improvement over Partial Vania, so great job there! The game had a lot of personality (even if the voice was text-to-speech, the script still oozed personality). The progression through the game felt quite well thought out with subsequent rooms being more difficult than previous rooms, and the jet pack power-up was a joy to use. I also appreciated that the janitor could just move freely about the building without any problems.
For some feedback,
1. It's a bit weird that my head / upper body goes through the floors above me. It's not super annoying or anything, but it does make things feel a bit unpolished.
2. The gas does too much damage and its hit box lingers for far too long. I eventually just started jumping over it (using the aforementioned body-through-floor shenanigans), but I felt like I would have gotten annoyed with the wait times had I not been able to do that. In terms of hazards, the spikes which rose out of the floor were also a bit on the small side., so I wasn't really sure if there were times when they were supposed to be safe to stand on or not.
3. I was a bit unclear if I was dealing damage to the final boss or not. Previously I had gotten feedback on every water gun hit because they were one hit kills, so when I didn't hear any sounds on hitting the boss I wasn't sure if my lasers were getting through or not. In an ideal world, there would probably be an impact sound for the boss and a ricochet or metallic sound for shooting one of the orbs. As for the orbs, they were probably too random for a proper boss fight, as is I just kind of hovered on the left side of the screen where they didn't seem to be able to hit me. I think fewer orbs or a slower movement pattern would have helped a lot with making feel like I could use skill to defeat this boss.
Overall though, I'd say this is one of the more coherent games I've played so far this jam, there was a narrative thru-line throughout the game, the character had personality, and all of the power-ups were well messaged and telegraphed. Good job!
