It's a pretty barebones loading sim with poor physics. I picked this up just to familiarize myself with the general concept of a forklift outside the job, not expecting much realism, and it still let me down.
My biggest complaint would have to be poor weight distribution for both the pallets and the fork, they both feel kind of weightless and are too easy to knock over. This is especially the case in first person, you have to get awfully close to the pallets to identify them, which usually leads to knocking them into the air and lodging them to the ceiling(?!), softlocking me out of some missions.
Second biggest complaint would be the lack of a first person view from the driver's seat. The first person view between the forks sounds like a good idea until you're actually carrying a load in a tight space. At that point, neither the 3rd person camera nor the fork cam provide decent coverage of your load, so you're basically guessing as you place it.
Other than that, it's okay, but I would recommend trying the other sims on Steam before this one.
