A fun and quirky game you made here!
I love the chess puzzles at the start - simple, yet well executed. I did however find it a tad jarring when I was forced into a fight like that - I think this game's design is much better suited to being story driven with puzzle and riddle elements powering the main gameplay element. The battles ended up feeling a little out of place and unnecessary.
Overall I did find it a fun and unique game experience. Kudos for making your own assets too, I know it's not easy and takes a lot of effort. Thanks for making the game and sharing with us.
