Unlocked at rank 10, two players can work together to beat a game, with a set map and difficulty, of Bloons. In co-op mode players can transfer money between them opening up new possibilities of gameplay.
The gameplay in previous games (TD4 and lower) was a bit laggy at times, luckily TD5 has cleaned up the graphics to make them a bit more simple while also allowing for new designs that differentiate things in the game in order to make it easier to tell what is going on. The cleaned up graphics also allow for smother gameplay due to them using less resources, meaning no more laggy gameplay.
There are microtransaction in the browser game for things such as in-game currency, tower buffs and progression locked towers. While the game can be played completely free, it will be much easier to play if you are purchasing content that makes the game easier. Some may see this as pay to win.
Due to the fact that the player can not mine upwards, there needs to always be an avenue of escape to get back above ground. Whether this is leaving enough fuel in order to fly up or leaving dirt laid out in a certain way that the player can climb up.
Having this element of complexity through puzzle solving adds a deeper level of gameplay, which is great for the non-casual crowd.
The story is told through mysterious transmissions that the player will receive at random, making for an intriguing story that is slowly drip fed to the player, which is a good reason to keep playing as to find out what is happening.
Each time the game is started new, the dirt that one will be mining in is randomly generated. This allows for a new experience each time played but also a way to make each individuals experience different. This way the game has a longer shelf life thanks to each experience being different from the last.
There are two different control schemes for the game, the player can use the arrow keys or the mouse. This allows the player to choose what works bets for them while also providing good controls for both.
Users have reported to being able to beat the game in around an hour. While the random generation allows for some replayability, the time that this game can be beaten means that a single play-though can be finished easily in one sitting. So for those looking for something to sink more time into, may want to look elsewhere.
The musical score along with the sound effects in the game can become annoying with time as there is little variation, meaning the sounds and music repeat over and over again, which can be frustrating.
While after 15 clicks the game can play itself, the constant goal of improving how many cookies one can click is pretty addictive in that there is always something to be improved upon.
Each upgrade costs more and more cookies to purchase and each hidden upgrade is not made available until you reach the amount of cookies it costs, so no matter if you need 100 cookies to purchase a new Grandma or a trillion to purchase some other tool you will always be left feeling like you just need to reach that next milestone.
Incremental or as some know them "idle" games are not always received well by those looking for something with a bit more skill needed, basically the game will play itself at some point and from that point forward which can be pretty boring. So for those that are not interacting with the game that often (no clicking, no checking in often) it can be less of an interactive title than what some are looking for.
