Hey, this is Torsten from the Malmö Jams Too team.
Time Trackers is an player versus player arena game where the base mechanic in the game is the ability to go back in time by methodically retracing one's steps.
Concerning mechanics and the game itself, it's great you took efforts in keeping the most playful elements of going back in time and still keep the game engaging. Though I would suggest you find some ways in constraining some aspects somewhat, where (for example) the limitations are for walls and obstacles being placed other than the corners of the board. This can be done with a modular board, or if actual limits are placed on where and how walls/obstacles are placed before the game begins.
In terms of practicality, you may want a pdf file of the assembly instructions as well for convenience. You may have to add diagrams to the rules you have produced, or perhaps a video will greatly benefit those who wish to understand the game clearly. Do not forget to add your teammates to the jam entry and game, setting them as contributing as well.
Overall, Time Trackers is quite intriguing mechanically and gives thought to how to tackle mechanics which have high flexibility. I noticed during the jam how there was a lot of testing and trying things out. You worked hard! It was cool to see a game that had a rough testing phase actually become a game in the end, so I applaud the efforts made. :)
