Last few levels are genuinely really cool with awesome well designed mechanics. I'm a big fan of the glitch effect with 0's and 1's, as well as the one with code written out. I think the flashing rgb and tiles when platforming feels a bit out of place as it doesn't really change the difficulty very much. I also think this game could benefit from some fancier sprites and tile mapping, and maybe some 1-bit centered graphical processing effects. The game crashed for me near the end of the last level relating to calling the method 'queue_free' on a null, as well as some audio errors making me wonder if I missed out on any music or sfx there, but overall I like this game and the story :)
