The game is enjoyable however some of the rules are unclear or dont make a lot of sense. Some levels feel flat out impossible. I did lose the progress with the Christmas event and had to start again and now can't finish the levels and tasks. I haven't spent any money but have still progressed. It's slow going once you get to a certain point though. Some more levels would be great!

Loved this game as a kid and I still love it today. It brings back a lot of great memories while still being fun to play now. Even though it has a few rough parts like crashes or a better list of spoil for finding baddie bonuses atc. but that don’t take away from the overall experience. I genuinely enjoy the game and hope the developers continue to update and improve it in the future as it does lack bit of content or something for replayability.

I really love this game, but it has some annoying issues. Sometimes when I'm playing a level, it will crash out of nowhere. I have tried uninstalling and reinstalling the game as an in-game pop up suggested, but the issue seems to persist :(

What’s new

This version fixes a calendar error that unintentionally caused our "Holislay" Event to end prematurely after the changing of the New Year. The special event is now working again, and we have also extended the end date by two additional weeks. Thank you for playing Castle Doombad, and we hope your New Year is off to a great start!
