First off, thanks for taking the time to find these errors. I really appreciate it. As for the speed issue, it's set at one lower than normal walk speed, so won't be able to do that. I'll mess around and see if I can make it more reasonable, though, since, yeah, it is a bit slow and the tutorial is pretty tedious to travel around.
First picture's intentional, just unfinished. It's meant to be an alley, and the blue's just placeholders for things like dumpsters and other things. A lot of the random solid color squares are usually placeholders in that world.
Second one has been something that gives me trouble, and I think the solution lies in using events for certain corner pieces, but I haven't tried it. Trust me, it's been bothering me a lot. In that instance that end would lead to another map (though I can't believe I didn't notice the sunflower area was visible from that side, only meant to be visible from the right as a hint), so I should probably raise that area a bit so it doesn't lead to that confusion…
And yeah move events in my game are weird. Change one thing and everything breaks so I keep having to find ways to not break everything. Maybe it's from the walk speed being set to a common event? Just modify the common event to change the speed.
Thanks for pointing those things out though. Also, yeah, there are a few areas where I forgot to remove teleport events. The panorama one is weird though, it was a placeholder image that I thought I got rid of in all the maps, but apparently I didn't. The area is unfinished anyway, so at least you aren't missing much.
And sorry for any errors teleportation might cause, really should've made sure they were all deleted before uploading.
