Good game! The concept is really neat, having control over the timer is awesome, and your implimentation of the timer mechanic works very well ! Unfortunately, isn't immediately clear how to use it - a tutorial would have been very helpful. The backwards and forwards time movements are well done, but unfortunately not very helpful in practice, maybe some puzzles that were based on them could help? Either way, congratulations on getting a project finished in time for the jam! 4 days isn't a lot of time to make a game, and its awesome that you got a submission in.
