The most obvious solution imo is to offer a free trial mode. If it fails during the free trial then don't buy it.

Steam is quite generous about refunding games, either because you purchased them accidentally or they didn't run correctly or any other reason, as long as you don't have more than a few hours in the game. I think that's a much better approach than having to implement what's effectively a DRM system in software, or a completely separate trial binary containing only part of the game.

Last I checked the limit was the minimum of "2 hours playtime" and "2 weeks after purchase"

Again, last I read, Steam is quite generous but will probably flag your account if certain patterns emerge (probably through some ML-alchemy).
