Thank you very much for playing the game. You're right about the ambiguity of starting the game and it looking like there is nothing to do. I didn't have time to put in a tutorial and I naiively thought the white button at the top left is enough.

Are you saying that you prefer larger blocks that take longer to break than smaller ones that takes less time to break? I am not questioning, I am just trying to confirm. Because at first that was the way I went but I felt it might get boring so I divided each tile into 4 and reduced their total "HP" with varying "HP" per tile color.
The energy replenishment is at the base but if you ended up depleting energy in the sectors you are soft locked, I am afraid. I did think of a way to resolve it, I just forgot I didn't fully implement it and it was too late after the jam ended that another person pointed it out.
Really appreciate the feedback and that you tried the game!
