The Big Hiatus is over, and Stage 5-1 is nearly finished. Stage 5-3 is also finished, it's very simple. (Zerg rush!)
The game now features approximately 18 minutes of gameplay from Stage 1-1 to the position that Stage 5-1 currently sits at (about 1:20 of stage), and then Stage 5-3 lasts for 40 seconds.
Just did a test run and died three times before hitting there to incredibly stupid things. x99.99 multiplier is VERY POSSIBLE. I ended up getting 889,000,000 points. I imagine with proper strategy I could have easily attained 1,100,000,000.
Other things that I plan on adding sometime would be joystick support.
I might try to resurrect replays from LS1, but they'd have to work and not be buggy as hell this time.
