F:MOD is a very short and rather poorly designed HOG.

On the plus side, it looks quite nice, it's 'funny bad' and putting together items in the HOPs themselves is usually a nice twist.

But overall it's pretty bad. The game is less than 2 hours long, even if you watch all the cutscenes. Some of the actions you have to take in HOPs are almost impossible to discern. At some point you have to find a star. There's no indication that you have to click on some lights in a certain order to open the flap it's hidden behind. I only found out by accident when i just started clicking everywhere. There are a number of other instances where even a 'HOG-veteran' like me didn't know what to do. For instance, an item is hidden behind a steel grate but you can't use any of your tools to get it. Near the end of the game you finally find the blowtorch you apparently need. That's just bad design.

The worst part about F:MOD is all the items in your inventory. Halfway through the game there will be over a dozen and many of them will seem like the right tool for the job when they're not. Even worse are all the shape keys. The developers have a fetish for those. In a game that's only ~100 minutes long you get dozens of shape keys, often wildly out of order and with no indication that you have a complete set without hovering over them in your inventory. It got so bad that i just started spamming hint. There are dozens of shape keyholes and you can't possibly remember them all. You might get the first star-shaped key at some point, find the drawer it opens 10 minutes later and finally find the fourth key half an hour after that.

So yeah, unless you have a fetish for shape keys i wouldn't recommend this crap.
