Well guys, the last time I've posted a WIP of this game was when I completed the entire third round. However I created a first draft of the fourth round and I actually intended to share the new progress once reaching a very good result.
I was working on this game back from 2019 when my laptop suffered a serious problem that I almost lost my project! I didn't lose my most recent files but I lost most of my previous WIPs from the previous stages.
Long time ago, Viewer made a WIP reaching the end of the fourth round but the movie file suffers a desync during the second boss :\
I returned to the project a year later, just to lose my motivation after optimizing 4-1 to the fullest potential (not present in this movie file) and having some hurdle with the next stage. I'm not sure if I'll return to this game someday - 5 years have passed while I focused working on other games since then.
