Not a day into the game, think I'll have fun with it for a while.

Great idle/tower defense game. Once you get the hang of the progression system, the game takes off. One thing I would note for beginner players: do not try to buy too many towers on your first play through. The prices climb exponentially with little damage boost to show for it. Stick with one or two towers until your first reset or else you'll spend forever on waves 1-50.

Good game with a few flaws

This game is extremely fun and addictive. You can definitely break wave 500 within a few days.

Unfortunately there are some flaws like other people pointed out. Removing ads doesn’t work, Offline progress only triggers if the actual game is quit (so you need to clear the game from multitasking).

A more serious issue is the end game. I wish there was a bit more content there. The ability to swap towers would be great. The speed up enemies option also only speeds up enemies and not your towers. This is fine but I wish it were even faster since the game doesn’t seem to progress when you are offline.

I don’t really see this game as an idle game due to the above issues. Never losing is a cool mechanic but the game has to be open for most progress to be made.

Everything I want

This game is great to play and have fun with. It can pass the time and you find yourself really wanting to progress without it being impossible to do so. Also amazing that you earn gold while the app isn't even running so when you come back, you have room to progress. 5/5
