Is this... my game, just 2d? No, a different game, but I was scared for a bit when I first looked at it. I like the simple aesthetic, reminds me a bit of "Into the Breach". There has been quite a few games with a very similar idea, some of them looking more polished, but I very much appreciate two things about yours.
- The puzzles are very cleverly designed. From the get go, they are a fair, but tough nut to crack.
- You went for the isometric perspective, but rightly chose not to allow player to move with arrow keys or WASD, instead allowing them to click on tiles to move to them. A lot of games made WASD controls that do not map to the isometric grid (which, in turn, allows you to see 3 sides of a die, allowing you to calculate the other three). I personally went for a "behind the dice" perspective, allowing players to rotate the camera with Q and E, when the isometric perspective felt wrong.
Good job. Even though it feels simple, with no animations, you made up for that with very right choices when it came to user experience. Much appreciated.
