At the moment i feel like level 10 and 11 walls are a bit to expensive. The rest of the walls are fine and doable but level 10 ones, 3 million is almost the same price as the upgrade fro the cannon at th9 which it shouldn't be. I would like if you lowered the price for level 10 walls to 2 000 000 or 2 500 000 and for the level 11 ones 3 000 000 or 3 500 000. This would feel more balanced and better priced but not make them too cheap.
