I was extremely impressed with this game. I nearly gave up during the first level -- thinking that it wasn't a finished game -- but I decided to just click around and eventually I started to see the patterns. The storyline of the apprentice figuring things out that were forgotten felt really thematic, and it was actually the hook that kept me playing through this time of discovery, and I really enjoyed that feeling of figuring things out as I went -- it almost felt like Myst that way -- where you're presented with these undocumented puzzles from a world long-forgotten, and there is immense satisfaction in getting them to do something.
I think I beat the game (I hope I didn't accidentally click through the final cutscene, as it felt rather short, and when I tried to click "Continue" afterwards, it just went to a black screen?) -- but I really enjoyed the writing and the voice-acting. I'm very glad you didn't use an AI-generated voice for this -- your voice-acting was perfect, and it really drew me into the game. I think your selection and curation of the other AI-generated assets for the game fit together very well, and it was clear you put a lot of thought and care into this.
I don't think I ever learned what the defensive towers were for, and I certainly never got them to fire anything. My strategy for beating the game was to power up my flame generator and always keep a healthy stock of flames and just continually repair my castle.
Power up flames, then power up books, then build the towers, then work on the central beacon. That was my strategy, and it seemed to get me through the game, but after reading comments here, I'm sure there would have been better ways to go.
I really liked how you didn't hold the player's hand through this, but I think you're right -- that a few more indicators (such as hover-over effects, or possibly particle effects to draw the eye) would have helped to build a better intuitive sense of what things were going on. The "repair" icon felt like a "build" or "upgrade" icon, and it was a while before I learned that the bad guys were bad -- I thought it was letting me upgrade my towers or something, but it was difficult to tell. If the central beacon could crumble (instead of just fade away) -- or if there could be a falling stone particle effect -- that might give more indication of what's going on when the bad guys hit it -- but overall I was still able to figure things out and complete the game regardless.
Super good job on the storytelling and the cutscenes and everything -- it was very engaging, and I liked the discovery aspect of the game. It would be nice if there were more "cleverness" to the action of the game (like a match-3 game having some sort of strategic opportunity that could arise) -- as it was, it felt very mechanical towards the end, and I would alternate clicking between the same three spots (flame, book, repair - flame, book, repair) until I could charge my beacon and end the level. Once I figured out the basic mechanics, there was little reward for remaining mentally engaged.
Overall, I really loved the game. The storyline and writing was superb, and the graphical style and all of the elements were very cohesive. I felt like the game held together incredibly well, and I really enjoyed it. Great work!!
