Thank you for playing! I wanted to tell a story about this unlikely duo but leave the rest up to interpretation. It's natural that players will have some unanswered questions like, "who exactly are these people?", "why is he/she doing that?", and "what's going on here?" The only thing that is clear is that the knight and witch together stand more of a chance than either of them would alone. Even that much isn't really explained directly though. The ending? It's a little cryptic.
I agree that the last fight could be made less frustrating. There are actually multiple ways to do the first phase and the method you used was discovered second. There is a way to get past the first phase of the fight much faster and I should have hinted somehow at what that is.
I thoroughly enjoyed watching your playthrough of Dyad. This was the first real project I've finished since I started making games five years ago. As the sole developer, the game shares a special place in my heart and I'm glad you enjoyed it.
