the cows are cute!!
I like the interface of the game too
i think it would be better for understanding the game if it had a little text box when the player hovers the mouse over things in the menu;
also i think it would be good if we could sell the debris for very few money instead of you having to pay to remove them
(but I understand that having to pay to free space in the grid also makes sense)
one last thing - did you make this game with gdscript or C++? just curious about your development process.!
overall it's a fun game!
