Just a heads up to anyone that wants to play this, the switch version runs very well on the high seas. Just finished playing it for the first time and started rdr2

I have always done it the way in the pic above, but I just found out recently that you can just turn it 90° and cut it in the manner you're describing. So if you are using the same type of can opener then you could probably just turn it like in the pic and try it that way.

IMO it cuts better your way but also leaves a more sharp top on the can

It's a tough fight, especially the first time. Firecrackers help a lot. This boss is required to advance the story, but if you're struggling with it, you can just leave and do a ton of other stuff before doing this fight, that'll help you level up and get stronger so it's not as hard of a fight.

Aspyr does remakes/remasters and ports of games, the stuff listed on their page should all be games they've remastered/remade, or ported to PC/Mac AFAIK. That's why they have things like COD and Star Wars listed.
