Yeah, it's pretty fun. I bought it on the PS Vita when it first came out, then re-purchased it on the Switch. I haven't played it on the Switch yet, but I plan to do so and then get DQB 2.

I found that the Vita was kinda small for DQB. Playable, but small.

I'm also replaying some of my GB, GBC, and GBA games from a long while back. I need to replace the batteries in some of them, though. I'm currently modifying my Game Boys to make the screens light up (since the originals of course don't light up at all). I don't like those 90s "worm lights" that cause a glare on your screen...
