First of all, welcome @Gaining_Goals. There are a few different things you can do if you’re interested in seeing if a user has some other posts. If you simply highlight and click on Somchu’s name on a post you can bring up thier profile by clicking a second time on the banner that pops up. In thier profile you can see things such as, top topics, replies, and links. This might give you atleast a place to start in searching out other games by the same dev (if they have any).
There is also a user maintained list of games in which anyone who has reached Trust Level 1 can edit and add games to the post. The list is does not contain all the games on the site (yet), but relies on members of the community to help fill out the list.
With all that said I believe @Somchu has one other game The Lipomancer’s Ruins.
