Very cool game! I like the visual concept, the shrinking play area due to your own bullets feels like there are consequences to your presence in game's world. I had a thought that the red dot pollutes the circle, but it has to do so to survive. No matter how much it tries, it eventually loses.
Nice port! I haven't played this game in a long time, thanks for bringing back memories. Funfact, in Poland this game is called Chinese. + I think something glitched, when I hold X I can move forward without any limits.
