Find the Code Doors 🔢🚪20 rooms completed play through, guide part 1

This is really good but its hard and I’m stuck on some rooms I’ve opened 20 of the doors including tutorial, which sounds odd considering the details for the game says first 15 rooms!. I am stuck on some rooms they are hard especially 'moving wall' and the wood Obby, i just can’t pass them I think it’s maybe device specific and using a touch screen letting me down, friends have tried they also can’t pass them. I have sent a friends request to the dev I hope to talk to them about possible improvement maybe adding buy me clues, possible making Obby easier for touch screen user sake. maybe some way to know which rooms are completed, Also the travelator in middle is awkward maybe make it narrow or lose the gap in middle, making path wider either side so you can stand on the edge by the room. If you read this dev please except my friend request and thank you for game, I really enjoyed it! 28 ROOMS UPDATE! I Have met the Dev of this game now, which was cool :) i was trying out the new update 28 rooms update at the time, I hope to speak with him again about some possible changes. since the new update i have completed 2 new rooms and progressed with other rooms i hope to have a complete play through soon, the moving wall and obby across the lava i hope he will make easier for players.
