I haven't gone too far in the game, but after replaying the game, I did find some issues that are either new or have been in the game for a while so far.
1. This Gally's overworld sprite is waterlogged, but her VN art isn't. https://postimg.cc/YvGRTc4S
2. I'm unsure if this box in the bottom left is obtainable unless you need the bounce ability to get to it. https://postimg.cc/XZBPKGKQ
3. There's an NPC that does nothing in the area where you avoid Nessie until the water is drained. https://postimg.cc/qg6jHSvN
4. The NPC that teaches you how to swim in the area still remains down after you've learned to swim and then drained the water. Also, for some reason, there's an extra floatie when filling the water. https://postimg.cc/PNkkCBFw
There're some ideas/changes that can be implemented in the game.
1. When you first fight Luci in the beginning of the game, her battle art could be changed to the same art when fighting her the second time after rescuing her. https://postimg.cc/Ny7Zm0n2
2. When you give Polly the mega potato after meeting her for the first time, make Nessie have a longer time eating Polly that Brookes would catch Nessie eating Polly before running/swimming away.
3. Make a dialog update to have some of Polly's and/or Luci's interaction in the Seal of Flesh, Floater's Forest, etc.
That's pretty much all I have so far. I just like to know that if Nessie is still planned to be a joinable party member (sorry for bringing it up), what would be the conditions to have her join, other than sparing her after fighting Nessie?
