i'm Philipp and i'm the developer of STOMT, a platform that combines feedback management with community building.
Means: You can collect feedback in-game and manage it on our platform, where your users can also engage with each other.
We're searching for more game devs to try out our Unity 3D and Unreal Engine Integrations.
Link to the Unreal integration (just on Github): Stomt.co
Link to the Unity integration (already Assetstore): Stomt.co
Costs: Free (we will offer premium features at a later point of time, but the basic will remain free forever (similar to Slack)).
You can signup up with your game here: Stomt.com
So please, please, please use our integrations and tell us on our platform or here, how to improve!
PS: Both integrations are open source on Github and our API is public too (https://rest.stomt.com) - and we start dancing in the office for each pull request we get.
