Absolutely brilliant entry, I loved the art it was sooo cool looking and very clear.
Took me a bit to realize I had to click the shield and shooters, but the number on them helped out alot.
It really surprised me in a OH WOW moment when the invader shot the shop icon making me unable to buy more money makers. a really "oh they thought of that" moment.
I do wish the shooters were automatic tbh, aiming was a little awkward and not exactly that fun imo. I think it might have been fun to have another row and autofiring, then you just try to amass power and economy as fast as possible rather then having to aim.
I admittedly havent beat it yet, but I plan to come back to it sometime to win. Takes a long time to win I found, but was still really really fun.
I think it might be important to make the player start with a money generator tbh, cause my first run was me buying a shield then... not having any money. PvZ addressed this by having you start with only enough money to buy a sunflower, maybe you could do something similar!
Really awesome entry, had fun and surprised me!
