File size in this type of game has nothing to do with game length. Time to beat is around 15 hours.

I wasn't implying file size = game length, I posed two questions:

Is it a Demo (due to small file size), how long is it (time to complete) which you answered with around 15 hours so thanks for that.

I'll wait for the GOG reviews and see if it's worth picking up in a sale.

Time to beat info has been updated. The game length is around 8 hours for a normal run.

Picked it up in the Winter Sale and now experiencing freezes when playing as Herman, hopefully the devs fix it!

No problem on my side, was able to beat the game in around 11 hours, no freeze.

Windows update 24H2 broke the achievments and cloud save for this game. I rollbacked the Windows update and got both achievements and cloud saves to work again (I unlocked 100% of the achievements).
