Fun game, although endgame sucks when you just place and harvest radish in masses. While this is the fastest way there is an alternative that takes a bit longer, but is way more stress free. Just place an bunch rabbits with the cog. Each set costs 90k and produces the same amount in one harvest. I had 5 sets which allowed me to get the 900k for a sushi after two harvests.
While the blocking ability is quite strong in the beginning, I think it's quite balanced in the later levels. From lvl18 onwards, i'm always struggling to keep the shield at a high enough lvl to not die constantly, while keeping it as low as possible to avoid wasting too many ressources on the next shield lvl. But compared to that the other weapon and armor upgrades are too expensive in my opinion. I only update very few each lvl and only invest 1 or 2 levels, because more would be a waste on the next upgrade. Especially health is kept just high enough to avoid being one shotted to damage the enemy at least a little bit each round. Updating the attack to be able to one shot enemies is completely out of the question, even to get the attack to similar levels as the enemy needs days of ressource gathering.
