Hey, I liked Dead Cells. I'm a limited-video-game-time dad. It is indeed a Metroidvania, a format that I love, but the procedurally generation freed me from thinking I had to inspect every last corner. Plus, I really enjoyed finding healing meats again.
I think I liked Kero Blaster even more, though. I had tried it on iOS before, but it's just too actiony for touch controls. On Switch, it feels great, and all the fine details are delightful. The little guy blinking when you hit the button to start the level, monsters faces when their hit. The music is really cheerful in that effective SMB2 way, though at first you don't know it's going to be cheerful, if you know what I mean.
