One of the best executions of the "one light" theme I've seen this entire jam, if not the best. This is one of those submissions that makes it really easy to visualize it as a finished game with just a little spit and polish. There was a lot of good level design especially when it comes to platform spacing and telegraphing that I really appreciated.
For things to be improved, the biggest thing I can recommend is that the hitboxes could have been a little more forgiving; I had plenty of stomps that felt like they should have been valid that ended up being deaths. Other than that, I did manage to accidentally escape the level geometry at one point (it was dark, I have no idea how).
A very good showing though, demonstrating some pretty strong platformer fundamentals. Top marks!
