No problem. I'm fairly sure that Oracle's platform can only be reached if the player flips or mashes the spacebar during their jump, neither of which are obvious things to do.

-I got this during the snipe fight in the blue area. I had 7 party members in total at this point.

-The game froze during this battle in the green area with the ledge that can be dropped down to go underground. Pressing numpad9 as suggested didn't do anything.

-Jumping off a sloped surface while moving up it can launch the player into the air. This gives much more height than either a regular jump or a flip. I also managed to do a similar jump by jumping onto a blue rotating platform and mashing the jump key, as well as jumping onto the side of the horizontally moving platforms and mashing the jump key while in the air.

-If an encounter begins while palmer or oracle are hovering (possibly falling as well, I'm not sure), the battle will begin with their hovering sprites being used instead of their idle animations. This will persist until they either attack or are hit by an enemy attack. Lo doesn't seem to be affected by this.

-Talking to palmer while the bottom of the screen is visible (only possible in the green area near the owl as far as I'm aware) will cause the dialogue boxes to be drawn near the centre of the screen instead of near the bottom. Jumping in this area while talking to palmer or the owl will cause the dialogue box to move downwards once Lo reaches a certain height. The box will then move to its initial position once Lo falls below that height.

-There's also a graphical glitch which happens when talking to the squid in the afterlife. This doesn't seem to happen in the starting area. This seems to be triggered while the squid's dialogue is being written into the box.
