I'll tell you this, not only I used the same Kenney's assets you used, but also the idea of my game is really similar to yours, so, ya know, I mean, if you want to give it a try, I'm interested in your feedback.
Anyway, I like the idea (of course). From a technical point of view, I had some problems with the colliders, like the trees colliders where you have to take the sword. The game is short, but it could be interesting if you kept working on it post-jam. I think that you could have exploited your rewind mechanic giving more path choices, to give it more meaning for the player, instead of a one-way adventure (like, last time I did this, let's see what happens if I do this other thing and go this way).
So it can be improved by adding more variety to the gameplay, and it definitely has some potential. I notice the effort, good job!

I'm interested to check yours out. My inspiration was Minit, I knew I wasn't making the most original idea. I wanted to make it original with my own story with Interesting characters you could interact with. But I ran out of time for other characters and dialogue. Your idea of giving the player more paths is something I've been thinking about how to implement. Thanks for playing and the good feedback.
