Thank you for taking the itme to play it! We were aware that the tutorial auto playing would be an issue, but we didn't have time to make it be clickable to progress, so we compromised by adding a rules reference in the menu. That being said, if / when we work on the game further, we'll definitely give the player control over when they progress the dialogue.
As for performance, its Unreal and the lighting isn't optimised the greatest. Its quite dark, so we needed more lights to balance it, which meant they overlap and its tough on the GPU. We thought that would be okay, but evidently not.
Either way, thanks so much for your feedback!
