Converting knitting pattern in the round to knitting flat

Hello all you lovely people at knitting help, I wonder if you could advise me, I have found a free pattern on Raverly, Despicable Me Fluffy Unicorn, by Inga Beruer, but it is knitted in the round, while I am a fairly competent knitted, I have never ventured into knitting in the round, I am wondering is there any way that I would be able to adapt this pattern to knitting flat. Looking forward to any advise you can offer me. Thanks in advance.

It might be more fun to practice knitting in the round and then try working this pattern.

But, if you are going to knit it flat, add a stitch on each end of a row for seaming. Instead of knitting all the rounds you will alternate knit and purl rows to get stockinette. It may take a bit of fiddling but you can probably make this work knitting flat.
