I'm gonna rate + comment for timer tiles since that was the game you intended to submit. I lasted 307 seconds. after a while, some tiles stopped working, as in I couldn't place tiles on certain grid squares. it got worse as the game continued so I assume there's some bug where grid tiles think they're filled when they're empty. Despite that, it was really fun. even through the bug, I could lift up tiles to protect them from death which felt like a neat trick I wouldn't have found otherwise. a really unique and elegant idea. great job!
