Though the concept seems pretty good, the controls felt quite janky and the game isn't running very well on my end. I think other comments have explained it well, it'd definitely be better to get rid of the jump cooldown, have the dash cooldown be way shorter and work a bit more on the box grabbing. I also fell a lot in some of the early pits that were (I assume) impossible to get out of, and I'd have to wait for the light to kill me every time. I suggest making it possible to jump out of them, or just putting some big spikes for a quick death.
Despite all that, I can see there was effort put into it and the concept is well thought out!
