Platform: Mobile (Android or iOS)

Genre: Tower Defense

Estimated year of play: 2017/2018

Price: Free to play

Art style: Dark/gloomy, not colorful

What I remember:

- Tower Defense where towers could only be placed at fixed spots

- Had a hero collection/upgrade screen similar to Hero Wars

- Dark main menu – I think there was a gate/door with iron bars on the right side, and some kind of portal in the middle or left where you could start levels

- One of the characters/villains wore a top hat and looked dark and creepy

- FSK/PEGI 12

I've already ruled out: Kingdom Rush, Castle Clash, Hero Wars

Any help appreciated!
