Okay, so after doing a fresh playthrough to make sure everything works, I have my incident reports ready. This is on the RC1 build. The first picture shows a room that you can jump past the exit in to get out of bounds. The second picture shows the shark chase room in Cove Cave. The tiles to the left of Brooke are invisible walls. The spikes in the Seal of Wind being a soft lock I've already reported on, as have others.
Also, if you're trying to replace all monsters in the game with your own original designs, I found one you missed on the forest path of the Seal of Wind branch. In RPG Maker, it's the art for the Behemoth, though I don't know if you renamed the monster. If you aren't trying to replace all the art, but just happen to be using a lot more original designs now, then this isn't an issue. Either way, I'm quite pleased with the level of polish the presentation aspects of the game are turning out to be.
There is one other matter to address. When transitioning my saves from the older editions, the game partially breaks when trying to reconcile the old main character with the new one. Symptoms of this break include but may not be limited to the profile picture and animations being off. I don't know if that can be fixed, which might necessitate people starting new save files from here on. I don't mind it, since doing this fresh playthrough for testing gives me new saves to work with. But others might be annoyed by this.
