Looks a fairly basic platformer that could probably have been achieved back in the ps1/saturn era albeit at lower resolution. Given a choice between playing it on ps4 and having the freedom to play it on a portable or at home the Switch seems the better option for sure. Can't imagine anything is lost between the ps4 and Switch versions looks well below what both consoles are capable of.
That could be said for any Indie game.
I'm not sure any would be fair but certainly a 2D platformer with fairly retro graphics for sure. Cuphead as a 2D shooter looks a bit more resource hungry and many indie games are full 3D games too.
I guess that is my point though indie games like this are simply better on the Switch you can play them at the home for the full experience or as a portable game. One purchase price gets both experiences. It adds value to the Switch versions.
So it won't surprise me if we see this pre-order pattern repeated for many indie titles unless its a title that makes better use of the ps4's more powerful hardware.
