Quote of the day from Zanac dev Takayuki “Jemini” Hirono: "Often what the developers think of as easy or middling difficulty, to the average person, it’s already more than hard enough."
Have a good weekend.

"It takes a lot of hard work to make something simple."
I've spent the last week optimising enemies to free up more CPU time. It's improved significantly since the demo.
This will be a constant cycle of building and optimising right to the end.

I'm still working hard on Razing Core most nights, but nothing new I want to reveal yet.
The game play is beginning to feel connected rather than a series of disconnected challenges.

Badcomputer is back with another rock-solid Master System release that harkens back to the simple yet addictive Sega Card games of old. It's also as affordable as it is engaging, so there's no reason to not get it and platform like it's 1986.
