Thank you so much for the kind words!
Yes. I completely agree regarding the movement. The isometric view did make finding an intuative movement method rather challenging. An undo button is definitely a good idea, and one that I wish i had thought to implement during the jam. The hint system is also a good idea. I suppose it was difficult to judge the difficulty of the game without playtesters, so i naively thought they wouldnt be necessary.
Your feedback is very useful though!
Thank you for playing!
