Make More! is an idle game where you manage five factories where a grid of 3x3 workers make items for you to sell. You use that money, alongside a premium currency, to improve your factories and your workers in various ways. After maxing all of your factories and leveling them to the maximum, you restart the cycle anew from scratch, with a few bonuses - daily cash and boosts for the characters you have already acquired in a previous run. It's a neat little idle game and it does the thing I kinda like with free-to-play games; Letting the player watch ads instead of paying for some 'premium' boosts.
My biggest issue with Make More! is that when you don't have money to buy new characters or upgrade them, when you're just tapping along in order to make money for the next thing, you have almost nothing you can do, bar using a few power-ups that are randomly dished to you. In some other idle games like Egg Inc, you always had an upgrade to buy, or you would just tap the screen like mad to hatch more chickens, which was the best way to increase your cash flow. MM! has significantly faster automatic systems, especially in the later stages of your factory. Your workers take a long time to make these diamonds and tapping along does almost nothing, except if you get tap multipliers or speed multipliers, which last for a set amount of time that can be tripled if you watch an ad or pay some premium currency.
And they use that 'watch an ad' system liberally. You can watch an ad to double your money after coming back to the game in a long while, you can watch ads to triple the duration of certain buffs, you can watch ads to get some free premium currency each day. Since it's not a game that you can play for huge stretches of time, it's fine. You'll probably never be able to buy the more expensive premium boosts that way, but at least it's enough to get a few upgrades here and there. You also can get some premium currency by completing semi-achievement-like challenges. There also are daily quests to get some more currency and you also get big gifts with some more currency and medals - to boost your workers.
After a while you get the ability to hire robots to replace your workers and these can be further upgraded to give you even more money per item sold. Upgrades to your workbenches allow you to idle for longer periods before you stop making money, and when all factories are filled, you get 'boss rage' mode, which makes tapping really worthwhile for about 30 seconds. There are plenty of nice idle systems in Make More! You can unlock all of the workers and increase the maximum level of your factories, which scratches the completitionist itch. It's too bad that you're a bit limited in what you can actually do as the player, but it still was a neat little experience.
