Of course you can return the game like any other game on Steam. You have 2 weeks to return the game, if you exceed the 2-hour rule, a return is no longer possible.

Before you buy a game, it is advisable to check beforehand.

Remember that if you make too many refunds, your account may be excluded from the refund system and further purchases.

Answer truthfully when requesting reimbursement and do not attempt to circumvent the system with false information.
