This is a text based game, Primarily using just the keyboard, with the sale you can get the other modules that can plug in or play this as a standalone game for (WINDOWS) not sure if this will work on 1 through 9, but will work on Windows 10 for sure! This is also gonna be the "Core" of all other games as well in this series where this one will be overhauled alot when new Modules and games come out to always point back to this! You will make 1 account and be able to play same account across them all!
You basically : Do math, get about 1000 to 2000 correct answers, buy Attack and or Attack Rounds, and fight if you want 7 in a row before all mobs level up! Then repeat the process of another 1000 to 2000 answers and so on... You get score and money for every Correct math answer and every won battle, Beware of Dragons, they are strong bosses that have a 1 in 50 ish time of appearing so you'll likely destroy some Rats most likely 50 with good luck and hopefully no Dragons and be able to level up the best you can! The other modules allow you to auto farm money more or less (I'm adding pets soon) another module to plug in but this game here is complete for what it does exactly! And will be the spot you come to always level up your attack always and will be your main source of battles! Other games will have other mobs, but they likely won't give as good score or money like this Core game will! :)
