The Chronos Principle

Fantastic game, could be five stars, BUT the "place the black block" animation doesn't always start or complete, placing the black block at anywhere but where you want it. Fails the most frequently the first time you try a level, requiring you to reload.

One of the best minimalist puzzle games that I've bought for my Android phone. Maybe in my top ten. My one complaint is the sequencing of the levels: seems like a lot of extremely difficult levels are followed by extremely easy ones. Completely stuck on the second to last level. I've watched the walkthrough and I don't think I'm even going to try solving it. Seems pretty insanely difficult. But I guess that's appropriate for the second to last level, which is actually the last one. Somewhat unique mechanics. I've played other games like it, but nothing else does it in quite the same way.

Much of the challenge in this game comes from how the game requires you to plan ahead and execute actions ahead of time in anticipation of future interactions. Since past instances can interact differently with the level, it's basically on you to keep track of where your 'character' would be on the screen without any visual aids. This sounds difficult, but once you get the hang of it the game actually gets really trivial. I was able to beat it super quickly, and it never put up a real challenge.
