Wow, thanks for playing and the detailed feedback! I'm also a mega fan of dark aesthetics, and with very mild colorblindness, I often find that value comes a lot more naturally to my eyes, and it certainly saves a lot of work/preparation in terms of choosing a palette as you mentioned.
I also think you're not alone in your initial confusion 😅 a tutorial is definitely something I'll put some time into in my next jam (or at least a helpful guide of some sort), and I think your suggestion for adding the few buttons to the screen definitely would've made an easy addition for this entry, but was something I overlooked before submission.
The crosshair as well is something I think would be another easy add if I had some extra time, and I've really enjoyed hearing reviewers say there's future potential, so I may even look into building this into a more complete game.
Thanks again for the review, and best of luck to you too! (and sorry it took a while to get back to you, been a busy week haha)
