Agreed, originally I was planning on adding values when you hovered, a better tutorial and things like that, but I ended up having to attend to other stuff over the game jam period. Being able to see the tank and control board at the same time would also be great.
Also, thanks for the compliment and for enjoying the game :D
If the game gets enough positive ratings and ranks high enough on the game jam to where I feel there's enough interest though I'll continue working on the idea including improving the tutorial.
