Thanks for playing and the feedback! I'm glad you liked the overall concept and sorry that pillar jump section got you. The checkpoint system is definitely still quite a bit buggy, it does usually work but we weren't able to get a tutorial in time for it and it doesn't always do what it's supposed to. But usually it should work if you go to the elevator on the first floor and press E while standing on the elevator. But really wish we had gotten a tutorial/Press E to use message in before the end of the jam.
Thanks for the feedback on the lighting too! We wanted to try out a lot of the newer lighting systems with Unreal so admittedly we probably went a bit overboard or could have done better balancing the light.
