Now that @Cibryll has confessed to being Shane/Kim, I also need to come clean. The reason I joined was because I was trying to end the Vresun Conspiracy, which Cibyrll was the Mastermind of. I succeeded because the Aeonian Night finally ended as of August 1st so now we're just getting to know each other all over again.
Status: So thankfully most of the issues during playtesting were minor. I'm currently getting Diamond Dogs (Phase 2) sprites working correctly (the fight itself is now fully functional) along with other minor sprite changes.
Status: In every 4th level, there will gates that require a keycard found in the previous 3 levels. The scripting for it was quite complex but thanks to @Hina's help, I was able to pull through and get it done. I'll be focusing on the sprites now because those will need doing among other things.
Status: I'm really moving along with development on Gun v2 now. It's just a matter of scripting two major things and getting the pixel art done for some bosses before I'll be sending it for playtesting to reveal anymore things that need improving before release.
