One of the first games I ever played as a kid was Lander: https://classicreload.com/lander-full-game.html. This was like a perfect encapsulation of what made that game fun, without some of the more finicky bits. I appreciated the generous health - ended up running out of fuel on Level 5 and dying but it probably was my fault for being too reckless piloting. The sound and graphics were simple but very clear. I think it's really cool that you figured out procedural generation for this in such a short time - that's very impressive!
