Easiest way would be to get gogData.series_ids from game page (array of series IDs), and use link to add it to cart:
https://www.gog.com/cart/add/series/1613 (remember it won't add products you own)
There are also game IDs: gogData.gameProductSeriesData
I suppose that - technically - it is possible to create discount bundle that you won't catch with those series or on promo spots, but you will get a great part of them.
You could also look for bundles on frontpage:
gog-bundle="[ 123, 123 ]"
Or add all gogData.products from frontpage to cart.
P.S. Samorost 3 is a nice game!
