Such and awesome entry to the jam. It is probably one of the most novel and inspiring takes on the time theme I have seen yet! You have done an awesome job with this, well done!
I really loved the time economics aspect and the fact that not all deals were worth taking. It took me a couple of runs to understand this, but then it added a whole new dimension to the gameplay!
Similarly to what others have suggested, if you want to develop further on the project, giving the player an indication of when the timeshift is happening would be great, as it currently is pretty invasive. But this is a minor thing, and I think all in all you have done a super awesome job!
I hope you have had a great jam, I really enjoyed playing your game! <3
