Hey again. Key rebinding is now possible in the game!
Great to hear! Took longer than anticipated but will check out the game again!
EDIT: Ok so played the first stage and 'Castle'. Only one type of attack, no throws, holds, grappling. Simplistic pixel-style retro graphics which are fine (UnderTale famously has a similar style). The combat doesn't have much variety. Mooks and 'Boss' enemies just charge at you and spam attack since there aren't many other options. Movement is kinda janky at times (yay moonwalking!) but works fine even on a craptop keyboard. Recommended to use a controller if the controller works (or perhaps using remapping software like antimicro).
If this came out in the NES days? It would be awesome as an NES launch title. However, it would be blown out of the water by something like River City Ransom or even the original Double Dragon game ported from arcades.
As an early/demo type of thing it works though. If you want you can keep improving upon it until you have something worthy of crowdfunding and then go from there. If you get NESMaker or something and make an NES port you may get more enthusiasts who wanna play it on an NES (including James Rolfe).
Good luck! The 'success' stuff I said earlier was NOT sarcasm since I genuinely wanted you to succeed and improve! Nobody creates Mozart or Picasso on their first outing :)
