Interesting game! I had trouble figuring out some mechanics, although I think that was partly due to me having the bad luck of running into an enemy just as I reached the end, so I thought it was some sort of bridge-building minigame to reach the other side instead of some combat scenario.
Once I figured it all out, it felt like it had the potential for an interesting mechanic, although it was pretty clear that you ran out of time. I would to see what this looks like with a day or two more of development!
