Yes, it’s that type of game.
Hello. I’m Nor Treblig. You now know a person who has completed Flashback. It’s not a particular hard game, but if you don’t know people who liked those PoP-gameplay type of games you probably don’t know anyone else who has completed this game.
I, for instance, don’t know anyone who has completed any NFL, NBA, FIFA sort of game (assuming they have some sort of career mode).
I agree on that. I don’t understand that they didn’t even show one single screenshot titled “classic mode” or something like that.
I have enough 
to pay the electricity to power any PC video game I want.
Such performance concerns can be valid for mobile games, but complaining about this Unity running more inefficiently than the original Flashback using e.g. DOSbox emulation is ridiculous.
