Ok first of all kudos on designing a novel puzzle game. There's a good number of levels, and all the one I've seen are very well designed.
But man, this game is extremely difficult :sweat_smile: Or at least, level 5 is extremely difficult, fun enough to keep me trying for about 30 minutes, but I never got past it.
Anyway, it's a good kind of difficulty, so I've no problem with that. What I do have a problem with is the controls are unintuitive, and make the game really unintuitive to learn to play. I spent way too much time on level 1, just because I never realized I wait (T) while the previous timelines play out, but instead always just tried to break time (B) right at the start.
Obviously, it could use a tutorial level, just to explain the mechanics (or at the very least, tell the player step-by-step how to beat level 1, then let them take it from there). But I'd like to point my finger at the biggest problem: understanding the "T" control. It has two functions in two different contexts (while replaying it means "step forward", and while playing it means "wait"). So I have two different suggestions to try: I would either introduce W for "wait", or just remove the "wait" functionality completely, and remove the need to use it. Or, if I was even braver, I'd remove the "step forward" functionality and make the previous timelines start replaying one step per second automatically after rewinding!
Other than that, the game looks great and sounds great. I was listening to the music for about an hour (as long as I played) and didn't get bored.
Very nice interpretation of the theme as well.
Great job on this game! :)
