I love everything about this game. Slashing monsters is extremely satisfying and it's an upgrade game so of course it gets more awesome as you get further into the game.
What is or was the hardest part for you in this game? For me it was completing the quests that required remaining at a constant speed level for 15-25 seconds, even though after I completed all of them I was still asking for more.
I hadn't played the other game so I didn't get it at first, but it did give me a new game to play and I've since become addicted to that one as well.
If you enjoyed Knightmare Tower, I'm sure you're also enjoying the other game. The idea is pretty original. Besides, squashing gummies has become one of my favourite things to do after a bad day...
