• Optimization Update! - 29 October 2025

  Hi everyone! While recently working on Kitty Combat I came up with some new ideas on how to optimize the game, which some of it translates over to Error 259. That being said I remembered how some people would have fps issues and have about 30 fps most of the time..... which is like super bad. SOOOOOOOO, I just went back through all off Error 259's code and painstakingly optimized most of the main things that should be in theory slowing the game down. Just a reminder too, any updates will only effect the dlc/complete version of the game.👍 In other words, YOUR GAMES SHOULD NOW RUN MUCH BETTERRRR 🎉✨✨✨✨ Ps. Thank you all again as always for supporting me and my games! 😄

• Error 259: Blood & Bombs DLC (Coming Soon!) - 27 August 2024

  Hello Everyone! I'm excited to announce that development on the Blood & Bombs DLC has officially started and will likely be done sometime midway through september or so depending on how smoothly everything goes. This DLC is planned to cost $5 and contains: 2 New Playable Characters (Vamp and Shell) 2 New Alt Floors (The Boiler and The Arcade) 20 New themed Items 10 New Enemies (5 for each alt floor) 4 New Bosses (2 for each alt floor) 50 New Room Configs for every floor Keep in mind also that while I continue to work on the game after this DLCs release I won't be able to go back and update the base game since it will be overwritten by this. Meaning that getting this dlc will also come with constant updates, new additions, and so on while the base game will not when it's done. The same is said when another DLC comes out, just saying this in advance to clear up any confusion. Basically ju…
