Really nice concept! I felt like I was playing something in-between Myst and Wizardry, which is really high praise in my book!
I love the graphic engine, which throws me right back to playing dozens of DOS demos as a kid and delivers a compelling ambiance and sense of mystery to keep the player interested in the exploration.
I was able to win every fight by spamming "attack" though, and never lost a hit point, even in the "dangerous" final battle. I restarted the game to test it out and did lose some hit points but was still able to win by just spamming attacks - both times using the pre-made party.
I think that if you rethink the combat from scratch, you could definitely use this tech to create some very interesting worlds to explore. The old D&D games like Menzoberranzan and Strahd's Possession come to mind!
Being able to properly look up and down (or even mouse-sook) would've been fun too!
I encountered multiple bugs but nothing that detracted from the experience enough to even bother mentioning :D
I encountered a few decorations that were interesting, that fit into the game world but that were obviously not interactive. The "dimension door" left me puzzled though, would be nice to have to go through it after defeating the final boss :D
Goes to show how the simple graphics and ambiance were enough to deliver a sense of mystery that made me want to explore this tiny world! Would love to see the concept expanded to a bigger scale, with better (or even without any) combat!
