Thanks so much for playing it, I'm glad you liked it! :) No sound currently - as noted on the game page, music and sound effects will be added in a future version.
I apologize, I must have missed that.
On an unrelated note, and I guess I will find out anyway once this comes out as a template, but I was building a map with the school assets and tried comparing it to this game. I noticed that the placement of several of the objects (by that I mean where they appear on the tile they are placed on) were different from how they are positioned as they come from the steam workshop. Since I was having a hard time getting things to line up with each other properly, I thought I'd ask whether or not you went into the model editor and modified the assets directly, or if you used them as is and I am just missing something. (also sorry if this is confusingly worded)
