Very fun and challenging, one suggestion.

This game is a wonderful blend of strategy and difficulty. It balances everything very well. The blocks each have their own abilities which you can use to defeat different levels. To the developers: might there be a way for those of us who do not pay to play to get the other commanders that are currently only for sale? Could we watch an equivalent number of ads whose revenue is similar to the cost of the commanders or something like that? Like each ad makes you 10 cents let’s say and a commander is $19. Maybe we could watch 190 ads in order to get that commander? Have those ads be specific to each commander that must be purchased. You would have to click on the commander you wanted and would have to watch ads over time until you reach the specific number of ads for that commander, if that makes sense. Like no other ads you watch, like the daily ads for gems, or the ones for more tokens for the daily challenges would go towards the commander. You would have to watch a specific number of ads specifically focused on getting each specific commander. I would love to see this added, and I think it would benefit you as well as all the non pay to play players out there.

An actual GAME

This is not one of those millions of idle games clogging up the app store. This is not one more match-3 slider. This is an actual GAME, like a real-time strategy game with merging. It’s got a little bit of a tower defense feel, but you can move the troops at any time. The only things that you wait for are improving buff buildings and opening some of the treasure chests. There is no “energy”: It’s a game you can pick up and play for 10 minutes, or you can play it for hours without having to wait for your turns to recharge. They should charge for a game this good, but it’s free! If you like RTS or TD games, or just want something colorful and fun to play for a bit, this is one of the best mobile games out there.

Overall great game, removing endless mode 👎🏼

This is overall a great game, it’s a unique take on TD and most of the towers are different enough that you can change your deck to get different play styles every fight. As others have said you can play for 10 minutes or 2 hours, there’s no energy system so it’s up to how long you want to play.

The biggest con has come with the last major update. They removed endless mode and replaced it with the “Norbert League”. I understand the reasoning for adding this - adds some more progression, competition, and challenge - but I wish they would’ve also kept endless mode as I got much more enjoyment out of that. Maybe in the future they’ll add endless mode back. I took off 1.5 stars because of the removal of endless mode, if they can add that back I’ll gladly update to 5 stars because it’s a great game.

Lastly, the commanders. I have Amon and he’s not bad at all. I’d like an easier way to unlock other commanders but at least it’s possible to grind out the gems and unlock them with paying real money, which is more than I can say for most other games today.
