Content update: BRAINPOOLZ
Hello again, I've been hard at work making the new awesome content. The game is good, maybe too good. This is a problem and I have the solution: BRAINPOOLZ. It's bad and you will hate it so good. Die in the poison swamp with a smile on your face. Love that movement? Falling into the swamp takes away all speed and joy. How to not: don't fall into the sludge Best of all? I made the level mandatory for getting the blade, so you can't even cheese it. Unless you are a true BAIONGAMER and you have a save file with the blade already unlocked. Speaking of save files, I added save slots, a long requested feature that I avoided adding because it sounded too scary to code. Wasn't too bad but as always with save file related things, let me know if your save got wiped, it probably is still safe but the file needs to be renamed or something. After watching people get horribly lost in the early parts of logistics sector, I realized how badly it was designed layout wise, so that was now all changed. It should be easy as pie to find your way to new wonderful levels and gaming experiences. Let me know if it still sucks. Those who have heard of the source and the engine may be familiar with surfing. Yeah you can surf now, though it's restricted to only work on curved ramps and half pipes. You'll see what I mean. The surf physics work so differently to the ramp physics I had to make a clear visual difference or it would be very confusing otherwise. Also like 1 guy asked for scroll wheel jump so I added an option for that, enjoy the jump.
