Bloons TDX: CarlFilip19 Edition

Bloons TDX: CarlFilip19 Edition (its current name) is made by the titular Discord/Miraheze user CarlFilip19 as a mod of Ramaf Party's |Bloons Tower Defense X. Where the original game had secret/alternate upgrade paths for the towers, this mod replaces them with plus versions of them, along with the following:
 * Plenty of elements from Bloons TD6 and references to said game, like borrowed upgrades such as Permanent Brew and Flying Fortress. Several upgrades and upgrade paths are also moved around and revamped such as the right path of Ninja Monkey being about sabotage instead of katanas.
 * Tier 6 upgrades. The formula for their costs are: [cost of the upgrade]*[the amount of towers with the upgrade]^2.
 * Quality-of-life additions such as fixing the most common crashes with Bloonchipper, and the ability to change a Monkey Ace's path.
 * A few new Bloons like the NFMB (Not Four Monkey Business [sic]), a Bloon coming after the ZOMG.
 * Two new tracks, with one of them being based on the only track from Bloons TD1.
 * A new mission called "Modifier Madness" where you have to beat Monkey Lane on normal mode, except that all Bloons are of a certain modifier, including the MOAB-class Bloons.

Reception
Reception for this mod has been positive in its recent years, with praise for the mod's own artwork and its additions, even though its popularity has gone down, leading to fewer people reporting the mod's bugs.

How to install
You need to go to the Discord server Bloons TDX Modding Server to get the latest version. Ramaf Party only gives the link to the latest version on his website. Ask the creator for a link to the server, and he may give you a link depending on how active he is, but he is fine with you inviting other people to the server.
