Nice puzzle game that makes use of strategy. I hoped the checkpoints saved my memory as well, but it was all lost. It was a task that felt gratifying when completing the bell combination to move on. The zombies were too slow though.
I think I was at the boss battle (after the transition scene) and collected the first purple orb which "killed" the zombie...except, I still got damaged by an invisible zombie and lost everything, having to restart the boss battle, and even the final scene transition. (I gave up at that point though =w=)
Really smooth animations and eerie atmosphere though. The bell progression felt fair and it felt great when I got the bell that gave 4 jumps.
