Time Clickers is an idle game where you have to shoot at cubes to destroy them. Doing so nets you money, which you use to upgrade your pistol and to buy other guns that auto-shoot at cubes to destroy them. Doing so nets you more money, which you use to upgrade all of that stuff until you get to a level where the cubes have so much health that you can't get through anymore. But never fear! You get special Time Cubes at certain levels, and you use them to upgrade many stats, in order to be stronger, to be able to destroy more cubes. You get the idea!
The whole 'cube' concept is interesting. In clicker heroes, you just clicked at enemies and they died and you either got all of the cash they could drop, or none at all. Here, just breaking cubes net you some money, and that's cool. I kinda wish the game would tell you in some way how many hit points each cube has in a level. I know that yellow cubes have more than red and white ones, but the actual number wouldn't hurt. It's also useful in boss stages (each 5th and 10th level), even if you can't kill the whole thing, you might be able to gain money just by breaking small cubes.
The pistol you use by clicking has a few upgrades, but you'll get most of it by using cooldown-based skills, like shooting automatically, dealing more damage, getting more cash per cube destroyed, etc. There is an 'idle' mode that moves the reticule on cubes, but it doesn't shoot for you. Maybe there should be a way to trigger skills whenever they're ready, maybe there should be a way to make the click pistol auto-fire as well, albeit at reduced power. You buy and upgrade five auto-shooting guns, a single-target pistol, multi-hit flak cannon and spread rifle, a splash-radius rocket launcher and another single-target gun that deals more damage each 5 shot. It would be fun if you could see them shoot like you see your click pistol when you fire.
The way you upgrade these auto-firing guns is interesting since after a few upgrades you have to 'promote' them, which lowers their fire speed but lets you increase their damage past that point. It's a bit of a bummer to see your guns 'slow down' like that, but the increase in DPS makes it worthwhile. Time Cubes work with a few skill trees, and you'll want to upgrade different ones depending if you plan on idling a lot or actively shooting and using skills. Since I'm leaving the game on while doing something else, I'm concentrating on damage and gold. Although it might take a long time, all skills have maximum levels, so theoretically you could get to a point where Time Cubes would only give you +10% DPS, and nothing else.
To conclude, if you want to try a cool idle game, Time Clickers is one of them. It'll entertain you for a little while, at least!
