I played the whole thing! I love the level design, it's interesting and I needed to die a lot of times to figure it out. Sometimes I didn't even want to finish the level when using up a life, I just wanted to gather info. This is a very difficult game haha. Jumps have to be pixel-perfect in a lot of situations, and our rogue robot is not an athlete (or maybe that's me...).
Without fancy stuff, the simple graphics and story are easily believable. I'm playing as a robot, I'm time traveling centuries ago to get past what the guards and the landscape are hiding. Even the little tidbit at the end of the game, along with the end of some intense platforming, was satisfying.
I think this game is good for persistent players. Maybe changing the spacing of some standard platform jumps that do not require time warping would be a simple change that could retain more players.
Good work on this game!
