It’s close, but not quite

I spend $$$ so you don’t have too. This game turns into a very tiny endgame loop within days if you spend money, and is painfully slow if you don’t. Upgrades feel meaningless and overall the game starts to feel very empty.

You spend about 1min doing quick side events for money. Then let it idle away. Normally I’d be fine but you make like 1% more progress every run.. the card system is painfully slow if you don’t want to spend even more money.

There are better idle games, and better TD games. This game feels shiny and worth it at first but the wears off fast.

Dead game

They do not add thing anymore, They only want your money.

Ad Rewards

I don’t want to watch 3 sets of 2 ads to finally get the reward, besides that I’d enjoy the game

$50 for that package is insane

Get a grip 😂😂

Fun, but slow progress

I have played many tower defense games. I do recommend this one. This one is a bit unique and has some fun attributes that are simple, but add a fun layer to the game. I have been playing for several weeks causally as I can (no money spent, but watched many adds as I wanted to help with progress). The mini games are fun and add a nice layer to the game.

The issue I have is the progress is slow for World 2. I have been on it for about a week and progressed all the way to wave 50, but continue to get one shot by the boss no matter my health/regen/shield/etc. I would be good with some challenge, but this is a massive one shot (over 68,000 hp + 10,000 shield.

I have not unlocked all of the tower levels yet (I almost to level 4). I am hoping it unlocks something to help with the bosses. I have also maxed out most of the attack attributes.
