Thanks for your answers,
It's up to you to know where everything you used to make your game came from.
I know that copyright/licensing is probably the biggest concern when you make a game and use premade assets. We made sure to only include assets that are clearly labled as CC - BY and give proper credit, hence I'm pretty certain we are on the save side concerning copyright infringement.
We were rather worried about things on the user side, which are usually burried deep in an EULA. Are there any health or system damage disclaimers ( e.g. an epilepsy warning or a "fit for purpose" disclaimer) you should include in any case?
I know that you can't answer anything specific to the game, but I figured there might be some best practices anyone releasing a small game should know.
