This game looks pretty short and seems to have som Potential for a TAS. I think I'm gonna check it out once I get the time.

I made a test run: http://dehacked.2y.net/microstorage.php/info/1916406553/bio%20force%20ape%20testrun.fm2 In-game times are: Stage 1: 2:31 Stage 2: 2:13 Stage 3: 2:08 Total: 6:52 Notes: - You accumulate/retain speed even when rubbing against a wall/enemy. - You retain all your speed when attacking. - You can stop on a dime. - If you jump off ledges the last frame possible, you'll jump lower/not as far. For optimal distance, jump the frame before this. - I might have been able to skip one more fight in Stage 2. - You jump higher when in the white blocks in the Stage 3 (why?). - It seems to take a couple of seconds for the final boss to be damageable. I think the time of an optimized run would be between 6:20-6:30

Very nice work, and pretty nice to see the game doesn't take long to complete. If nothing else, I'd like to find out if there's a faster way to gain momentum than by simply running.

Well, jumping off the rope-swings launches you at full-speed even you were perfectly still the frame prior. L+R/U+D seems to do nothing. :( I still need to figure out how the combat works. For the testrun I just fudged it by alternating between high and low kicks repeatedly. I didn't bother finding out any of the frame intervals, damage values, or how the finishers compare/are activated.

I found a big timesaver.

One more thing that I need to look into before I start in earnest is to find out if it's possible to roll through this gap:

I'm looking into this because this roll in the final level is possible. I need to figure out if the limiting factor is horizontal speed, that fact that the final stage's gap has a passable block below it, or vertical positioning. The end of the semester/finals are coming up soon so I'll be putting this run on hiatus for a couple weeks.

(yes, the game really has an address that determines how many screens you are traveling per frame) General game notes:

Y-Speed
  Gravity
   - No buttons - 144 (subpx/fr)/fr
   - Holding A  - 48 (subpx/fr)/fr

  Terminal Velocity - 8px/fr
   - goes back to 7px/fr once reached
   - thus, hold A on certain frames to fall slightly faster

  Jumping
   - Initial speed - -(5px + 64subpx)/fr
   - Ceiling hit - y-speed = gravity

X-Speed
  Acceleration - 16 (subpx/fr)/fr
  Deceleration - 40 (subpx/fr)/fr
  - Pressing backwards - x-speed = acceleration
  - Same on air, ground, or against a wall

  Max Speed - 6px/fr + some (8? 16?) subpx
  - Gets rolled back to 5px + (224subpx or 216subpx) once reached

General Notes
  - Shuttle-platforms and minecarts override the speed addresses (they don't use them).
  - Shuttle-platforms "snap" your position to a certain coordinate.

Very nice work right there, I'm looking forward to the finished run.

As am I. I predict the run will be around 3-4 minutes now with all these new tricks. They really help make the game interesting.

I was going to say something like "the final run will be more like 5 minutes", but then my brain got working for a bit and this happened:

I suspect that this is the only TNT barrier I can skip this way, but this alone is like a 25 second timesaver. My new ETA is about 4:30. EDIT: Also, for those who are curious, here's some (objectless) maps of the game xkeeper made: Stage 1 Stage 2 Stage 3

Using the 2/2 falling trick I saved 33 frames on the first two parts where you fall (about ~25 screens of falling total). Then I somehow lost a few frames on the next section for some reason. I think I should figure out how to use macros/turbo so the falling trick doesn't kill me out of boredom. It feels like so much effort for something that will probably save only 3 seconds (at best). Currently the run on hold until I finish my programming final/pack everything up/fly back home. And by that I mean I'll start working on it again sometime around Friday/Saturday/Monday.

In light of the new tricks and stuff I decided to make a new testrun so I'd have something better to compare the proper run against: Link Stage 1: 2:22 Stage 2: 0:33 Stage 3: 1:31 Total: 4:26 For stage 3 I discovered that every TNT barrier is skippable, though in one case it might be (though probably isn't) faster to not skip it. Also, it seems that the timer doesn't stop until the fadeout begins, so for the last stage I run to the right so the little ape scurries offscreen quicker, even though I could have ended input earlier ("Aims for fastest in-game time", I guess). EDIT: I found the memory addresses for the in-game timers:

Stage 1:  8532fr  2:22.2
Stage 2:  1999fr  0:33.3
Stage 3:  5433fr  1:30.5
Total:   15934fr  4:25.56

Awesome. It almost seems like the skips in level two are intentional? If this is only a test run I'm really looking forward to an optimized version.

Judging from the position of the TNTs, I dont think it would be faster. Looks amazing! I cant wait for the final movie.

Stage 1 WIP I saved 241 frames (224 in-game frames). The savings come from the falling trick, lag reduction (rolling = less lag), a couple new strategies, and general frame-savers.

Stage 2 WIP 73 frames saved in this level (71 in-game). Biggest timesaver was skipping one of the ceiling glitches in favor of going directly onto the minecart (~40 frames). Another 7 were saved by jumping on a piece of minecart track (technically not, but that's what it looks like). The rest came from optimization. Total savings so far: 314 frames (5.23s)
