I recently heard about a pretty neat game from JackSepticEye on YT called Deadbolt, and after seeing him play some of it, I wanted to try myself. And it's a pretty fun game. Granted, it's very heavy on memorizing and perfecting patterns, but you kinda get into it after a while.

Here's a link to where you can download the actual game. http://hopoo.itch.io/deadbolt

Note that it's still in early Alpha, so no more than 5 levels are playable in the version I tried, but maybe it'll be completed soon.

And if you're curious, here's JackSepticEye's playthrough of it.
