Just played it, I loved the idea and the randomization is very high quality, I've tested resetting the game and the results were very nice to explore in terms of not being in a very similar pattern.
I liked the retro style graphic, it reminds me the commodore or nes era which is very nostalgic to me.
though the thing that was interesting but soon became bothering is line-by-line rendering which as an example I could see this in my mind like this, everything is rendered only for the first time but next time it is read from the memory and you have it rendered all at once on the screen. I think in this case not only the retro effect is still there but it won't have negative impact in the gameplay flow.
I'm looking forward to test the updates and future prototypes.
