### 4/5 — The latest version seems buggy

*2025-07-13, version 1.0*

I haven't played this in several years, and saw someone playing it on YouTube and figured I would see where I left off.

When I ran a couple of my previous solutions, everything executed quickly with no hitches.

But I didn't see the charts for the run summary I saw in the YT video (granted it was a PC copy of the game).

So I thought, huh... I wonder if there is an update that adds those graphs.

So I checked, and there was an update, so I downloaded the latest version...

But now when I run the same solutions that used to execute quickly without any hitches, now seem to freeze and hitch, and is not nearly as smooth as whatever version I had previously downloaded prior to updating.

So I really enjoy this game, but it seems to be broken in its current state for some reason. Please fix the hitches (or restore a previous version that did not hitch).

Previous version was definitely 5 star.
The current state is 4 stars tops, not a great experience.

### 5/5 — Awesome

*2025-04-04, version 1.0*

I’ve found out recently that I absolutely love to program things, even though I have no experience in it, nor do I know any programming languages aside from assembly code. I found this gem and it’s amazing, scratches the programming itch I have, and makes it fun. Definitely worth every cent.

### 3/5 — Good game, no external keyboard support?

*2025-02-13, version 1.0*

I know this game came out awhile ago, but even then there was hardware keyboard support on the iPad. I just hate that I have to use the onscreen keyboard, it’s so hard to do. Esp. since it’s a desktop game!

### 2/5 — Keyboard is a must for typing

*2025-01-05, version 1.0*

For a key about programming, lack of keyboard support is a big show stopper for enjoyment.

### 4/5 — Seems fun, but no keyboard support

*2022-12-30, version 1.0*

This seems like it will be a fun puzzle/logic/programming game but the lack of keyboard is really frustrating. I would like to see the game avoid using the on-screen keyboard, but if a physical keyboard is present allow it’s use.

### 4/5 — Just discovered this gem!

*2021-09-23, version 1.0*

I have been tinkering around with programming in various languages for years and stumbled upon this game while searching for a factory sim for the ipad(something similar to factorial).  Anyway, I have been up most of the night working through the puzzles and really enjoying what I have encountered so far.  I would definitely give it a solid 4 stars.  For a fifth star the devs would have to add keyboard support.  With so many options for keyboards for tablets these days as well as the amazing keyboard for the iPad Pro, having to use only the on screen keyboard seems a little clunky.  Maybe I am just being picky tho, great game otherwise!

### 3/5 — Magic Keyboard not compatible

*2021-08-03, version 1.0*

I love the game but on iPad it doesn't translate to touch well and the magic Keyboard doesn't work with it

### 1/5 — ???

*2021-07-03, version 1.0*

Game is literally unplayable due to only half the keyboard being accessible.

### 3/5 — -2 Stars for NO KEYBOARD SUPPORT

*2021-02-12, version 1.0*

I love this game.  I’d honestly give it five stars easy except for the omission of hardware keyboard support.  One of the main reasons I have an iPad-Pro is because of the keyboard.  As a software developer myself, with experience in iOS, I know for certain that this is some seriously low hanging fruit.  Please, add the keyboard support.  Although, I see its been over two years now of people begging for it... so, I don’t think anyone is listening

I hope the developer will consider some of their other games for mobile/iOS.  It would be great to see Shenzhen I/O in this format (as long as they include keyboard support).  ExaPunks would be awesome too!

Thank you.

### 5/5 — Who cares about the keyboard?

*2020-06-17, version 1.0*

I bought this app to support the developer because there are simply no apps that even come close to trying to help you understand computer science. The concept is easily five stars and I hope they keep delivering.
