Hello again (for the 3rd time XD), I've test out the demo again and I'll immediately say it, the map feels so much better now! It's moving so smoothly that it doesn't even compare to the lag I've felt before. I love it!
for the tileset, I'm not sure if it's fixed or not since I don't know if you intend it to look the way it is now. The cliff corner is gone and the other corner thing that's blue-ish is now green which fit with the rest of the tile, but the bush(?) thing feels a bit off because you can see perfect edge on the top left part of it. This makes the grid very noticeable and make the game look less polish a bit, though it definitely stand out less than before.

For the 3 or so second lag during the plinko... yeah I seem to not be able to reproduce it either. either it happens on random and I just wasn't able to get it this time, a pc problem (in which case then that's just me problem and not the games), or something that have been changed also just so happen to fix the lag. either way, if it doesn't appear then I'd say that's a good thing.
Last report! While I was playing the game again (trying to get the 3 second lag problem), I ran into another visual problem:

Just a heads up, the pegs are all there. When I drop the token, the peg that the token touches re-appear as normal and they all work normally, it just... rendered invisible for some reason. no clue why it's doing that but... it did, and now I got a broken-looking plinko machine XD. (also, by coincidence, the broken look feels quite in theme with the horror aspect that you got going on)
Since it's purely visual and doesn't impact gameplay, it's more funny than it is frustrating or annoying, but if you know why this happens it should probably be fixed. (unless you intend this to happen on very rare occasion? though the way the peg rendered back made me feel like it's not on purpose lol)
