Thanks for this! Trainer worked for me for keys/gems/coins. It doesn't actually work for steps, runs can still end after you run out of your normal step count. You can even see in the menu how many steps you really have, even if the counter shows 99999. Also noticed the trainer causing some glitches, one time every door I opened lead to a glitchy room with nothing loaded and you fall through the ground and end the day if you try to enter. Another time it caused some doors to not properly load, like when I had a lab and boiler room connected, the door in lab wouldn't actually open or show up, and I could rapidly lose steps trying to push through.
For the steps I use CheatEngine, its farely easy to get the step counter, but it seems to change each run. You get 5 values identified after 3 rooms and the last value is the actual step count, while the 4. is the previous step count.
game bugs out building rooms with this trainer, after picking, the room picker stays there like you didn't pick a room, can't pick anything else so it just locks you there.
