The best way to describe this game is "A HD remake of Pandemic with a sh*t ton of new features!" Simply put, if you enjoyed Pandemic, theres no reason to hate this game, it's better in everyway.
The music is good, however it can get repetitive at times.
The graphics (If you can call them graphics) are nice and bright, and every stands out so you know what is what, nothing blends in.
While Pandemic had 3 diseases, this game HAS A LOT more and creative ones, plus thanks to the Steam workshop, theres pretty much an unlimted amount of diseases you can play as, plus if you want to make your own, it's very easy to learn!
The game while simple and repetitive, it's still a lot of fun and has a lot of Easter Eggs in game, including a Minecraft reference and more.
However theres one downside for me, and that's you unlock some of the content by playing a disease in a specific difficulty, this sounds good, but most of the time from my playthroughs, some bullcrap keeps happening like the following.
I never get enough DNA points to stop the cure OR get the upgrades I need.
The game has an ♥♥♥ pull and the cure sky rockets while the upgrades don't help at all, they barely help.
Some upgrades feel like they do nothing, for an example I got an upgrade to increase lethality, but people die at the same rate as before.
If my disease has nearly no severity, it will get spotted no matter what... this is really unfair when I have a PIXAL amount of severity and I pretty much lose when I just started the game.
When I try to play sneaky and spread then kill, I keep getting random upgrades because my disease is evolving, this can help, but most of the time ruins the game for me.
I would have prefered to have all the stuff unlocked at the start and have "Beat this difficulty with X disease" just as achievements, rather then having it locked.
Overall it's a fun and basic game, if you enjoy Pandemic, theres no reason to say no to this game.
