They say an army marches on its stomach, but that was before incremental idle games got so popular. Now world domination is just a click or two (... million...) away, baby, in Deqaf Studio's Immense Army, where all you do is click yourself silly, both to generate more troops and gold, as well as help your army out against enemies. See, each building you buy generates a certain type of warrior, who can be made stronger if you've got the cash, and when you send them out to fight, their strength determines how well they clout enemy forces... who can be captured to toil in your mine for mo' money, incidentally. If you're not a fan of the "clicker" genre of games, chances are you might find Massive Army a bit too simple for you, though Deqaf Studio's vibrant, colourful art and characters does a lot to charm. You'll unlock more dangerous areas, discover artifacts with passive bonuses, and click your way through vampires, knights, and more. With a little more development, Immense Army might really hook an immense amount of players, but as it stands, it's still a cute, satisfying clicker for fans of itty-bitty deadly combat.
So, this is a very broken game. The captive system is underwhelming at first, but then becomes extremely overpowered. By world 30, my level 70 mine was making so much money I decided to start experimenting with how much money I could pour into it before it cost more than it gave me per tick. It was level 120. At that point, I had so much money I leveled my buildings from 130 to 220, which pushed me through world 45.
I then upgraded my units to 150, and realized that I couldn’t upgrade fast enough to keep up with how much money I was passively making. That power took me through world 59, where I stopped because my finger couldn't handle another upgrade clickfest. Anybody who has played this game through to the “ending” of world 300 is a saint or a robot.
TL;DR: You need “x10, x100... max” buttons, or your upgrade cost/power curve need to be much steeper.
The game does not end at 300 levels, numbers just keep getting bigger. It becomes a click simulator after ~75 levels.
For an idle game, there's too much involvement. You have to click on every battle - it should just continue to progress forward until you hit a dead end because you haven't upgraded enough. On the other hand, for an interactive game, the pace is pretty slow because you're waiting for battles, etc, in order to increase your army...
