Very sorry you encountered this bug. I've never seen anyone encounter it in the first game, and I was unable to replicate it on my end, meaning it's likely very rare. Still unfortunate, as I hate releasing physical products with technical issues.
I appreciate the feedback about the length. I'm glad you enjoyed the game despite that, though! I've been planning a larger adventure with Batty ever since the first game, which has evolved into my concept for Batty Zabella 3. I'm nearly finished the spin-off game, Bat-Son's Nightmare, so I'll be fully focused on her third game after that. I hope you enjoy the sequel!
Maybe my chromatic was flabbergasted by Batty's beauty :D
Don't worry, I work in QA on the side, so me encountering only one rare bug is actually a very positive metric. And it also can be FPGA related, who knows. There was 0 problems after this.
Happy to hear that BZ3 is coming at some point in the future <3
Thanks for the response! I'm always very happy to hear from people that enjoy my games. The series has been a huge passion project, so it means a lot when people share their experiences with it.
I've yet to try a Chromatic, but I do have the Analogue Pocket, which I originally bought solely for Batty development but ended up using a lot for playing other GB/GBA games as well.
