Lots of great stuff going on here for a simple platformer. Adding the additional platforming mechanics, paired with the box cursor idea, means that players are always needing to co-ordinate their movement. It's quite fun and decently challenging in a way that shows a good understanding of how platformers work and what aspects of their level design makes them interesting.
I thought there were a lot of neat touches to this game. I think the simple graphics allowed you to polish things in a lot of other ways. The kill count and the death ghost effects were some good examples of this. And like any good platformer the new abilities kept coming as the game progressed!
I think the only constructive feedback I'd give is that because the controls require the mouse and keyboard, some of the more complicated movement in the game can get a bit tricky, but I think that's part of the challenge.
Thanks for submitting this game to the 'A Dark Room' jam!
