Great game! Nice to have the difficulty option, and the more monsters option is INSANE! = DD Randomization is exactly what Dig Dug needed to avoid feeling oppressive, now you go into each round looking forward to what new challenges it will bring. I've already seen plus-shaped caves, and caves stacked one on top of of the other. : D And so far it hasn't done that mean thing regular Dig Dug does of spawning monsters exactly on top of each other so you go to inflate what you think is a lone monster and a second pops out from right on top of it and kills you--hasn't happened here. : )
An excellent idea that I heartily applaud; a great touch. : ) Also I noticed the little musical piece that plays when the player character enters round 1 in your game is slightly different and more jingly than the original arcade version (or at least, the version of that one on PS4)--very subtle but again a nice difference. : )
