I WANT TO THANK THE WHOLE DEV TEAM FOR THIS AMAZING GAME!!!!!!!!!! this reboot had a very rocky start. there were constant glitches, and it was literally unplayable. but now the glitches get patched before I can even say anything! If I have to substitute an OP boulder of doom for an amazing new world with great music, great new enemies, and an awesome, original world gimmick, so be it! In summary, this game is amazing! thanks for reviving my childhood! and I can't wait to see what happens next!

I love this game. I played it a ton years ago, came back, and was surprised with new content and improved fun! Even got super excited seeing they're planning on releasing a 2 and still have updates planned for Free 2 Slay. Instant wishlist on Steam and easy 5 stars for me on the app store. I remember there used to be a few bugs that made u start over some levels, but I've yet to run into them again + replaying through all of it again is surprisingly fun! I could go on and on, but I ran outta w

This is my all-time favorite tower defense game! The new Rogue mode is a neat concept but I find the difficulty level too punishing. I'm also eagerly waiting for Endless Knights & any new chapters. I know Castle Doombad 2 is heading to Steam but I prefer playing on my phone so I truly hope to see a release on Android as well. This is an AWESOME game & I hope the developers continue to support it for many more years with new content and updates. 😊
