### 1/5 — Does this work for anyone else?

I used to play this a while ago.  Stopped then re-added it.  Tried to play and it’s stuck on the first instruction page

### 1/5 — Buggy

*2022-10-31, version 1.5.9*

Can’t even get past the tutorial. Won’t let me make any wires to connect anything to anything, and I can’t skip the tutorial

### 1/5 — Broken on iPhone 11 Pro

*2021-04-30, version 1.5.9*

This app is badly in need of an update and should be removed from the App Store and recent purchases refunded. I can’t even get past the first tutorial screen because it doesn’t register touch events correctly.

### 1/5 — Doesn’t work?

*2021-01-06, version 1.5.9*

I have an iPhone 12 mini, and no matter what I cannot get past the intro screen.

### 1/5 — Abandoned App.

*2020-12-31, version 1.5.9*

Was great while it worked, but has not been updated in 3+ years and is no longer functional. Don’t bother downloading until there is an update.

### 2/5 — Super fun game, not maintained

*2020-10-27, version 1.5.9*

I loved this so much. My son found a game like this through his school so I reinstalled it on my phone to show him. Unfortunately it does not run on iOS 14. The scaling is off and I wish I could recalibrate the input in app so I could play it again. PLEASE FIX THIS FUN GAME!

### 1/5 — How to play this game?

*2020-09-01, version 1.5.9*

Why It’s not working on my iPhone 11 Pro Max. I just purchased the app and been trying to follow what the written instructions telling me to do but it’s doing anything.

### 1/5 — Does not seem to work

*2020-09-01, version 1.5.9*

The first screen you are shown is a tutorial that tells you to draw wires between components. It is not possible to draw a wire on the screen. iPhone 8+ running 13.6.1
