I'm mostly posting my review based on the Nintendo Switch version, but I presume the game-play is exactly the same.
It's always nice to see new Wonderboy-ish games being released, but I am slightly disappointed in this game. Its described as taking "directly from the 16 bit era", but sadly, the only thing taken from that era is the amount of colors on the screen. All the rest feels like 8-bit NES or Sega Master System instead. I haven't gotten that far into the game but the music sounds repetitive already, and most sprites appear to only have 3 frames at best.
I will probably still enjoy the game, but based on what it is, a 8-bit Wonderboy clone, and not what it appears to be boasting about (16-bit).
