The designer's not kidding about the original game being from 1958. It was originally played on an oscilloscope, before we even had computer monitors, how cool is that? I always wondered how it would feel to play it, thanks so much!
I'm thrilled to have some solid contemporary classical music as the backing score for this game! And sponsor, thanks for answering the questions. Many times it's more important to see our concerns addressed than it is to see someone get everything right the first time.
I very rarely give five-star ratings. Burrito Bison 1 got four stars. This, on my third playthrough, definitely warrants a five. You've got the right balance, a simple but addictive game mechanic, and just the right learning curve for achievements and upgrades!
I enjoyed this a lot. It plays to those who think in parallel rather than get tunnel vision.
I might tweak up the graphics a tad, and space out the spawn rate more as the waves get larger. Other than that, I think the simple gameplay works in your favor!
