Thanks a lot for the feedback. What you told me here is what returns to me every single game jam... Playtesting. I always master my games during development and feel like they are too easy, while in fact, it is just me getting better. I never have the time to get second opinions too. The pallete is something I screwed up I believe with the introduction of my "Concrete Wall". We were short on time and I had to create an asset XD
Thanks for this long evaluation and I will definitely work on improving in these aspects!
