Should just make the Unlock Pins be equipable in the menu button slot. That way it adds flair that stays in line with the game (Pinning the unlock to the menu to use it), removes the pin from the tray and cleans up the space.
No one wants to play a "slow burn" browser game. Intentionally making it impossible to get anywhere in the game unless you buy your special currency is a terrible model for a game. Being away for 8 hours for a couple grey monsters and a handful of gold is just going to push away players. Ive already changed my votes to 1 star and deleted this off my devices since the devs would rather be CnNTs about it.
@MichaelChandra i didnt know that. But Im still more meanign being able to throw down a couple at a time. I dont want to blow all my energy at once, but i like to place a few zombies in each house and let them turn the residents. Makes it faster clearing imo. So an option/upgrade for like 5 zombies per click would benefit me.
Tooltips. Its a P I T A trying to figure everything out from pictures. Also your resource bar checkbox works when unchecked and disappears when checked, this feels backwards.
I just want to say that my favorite tiny mechanic is the flying things bouncing off the screen walls when you hit them too close to the end. it does make me laugh.
