This one is weird, as in it’s primarily developed for the PC, but with NES limitations. They want to have it ported by an external contractor to NES if some stretch goals are reached. (Broke Studio, who did Micro Mages and Twin Dragons.)
Stretch goals were reached.
The tiers are a mess to follow, but if you want the CIB NES version, £45 gets you a white cartridge, and £100 gets you the translucent pink cartridge and other trinkets. Different pricing are given throughout the description, but ultimately it’s the Kickstarter side bar that prevails.
