Glad you have been enjoying my I,Robot playbacks + thanks for the recognition
Atari master David Theurer put a great deal of effort into this overlooked title and I am glad I could share some of it's complex level design. Once you get past the difficult to master controls and put aside the unfair random enemy spawning/floating head deaths it's a really fantastic game with it's advanced for the time graphics engine.
For easier viewing here's the video playback of this 825,730 point game on my Youtube channel :
And here's another playback of the some of higher levels I did recently in a 971,509 point game up to Level 99 (via Demo mode warp to Level 79+ after building up the maximum 4 extra lives on Levels 1-4 first) :
It's hard to get much farther past 800k after it stops giving out extra lives every 20k at this point because there are so many ways to die outside of the player's control. You can still earn bonus lives by collecting the I,Robot letters after this but that takes too many waves (7-8) to earn them while dealing with all the potential ways this game can steal lives from you even if you do everything right.
The end of normal bonus lives after 800k, along with the unavoidable random enemy deaths that come up inevitably, plus the no room for error tight bonus time windows on some higher level mazes like level 99 for example is why I am not sure the 80's WR of 1,383,959 points was done playing level to level. The player just does not have enough lives available to weather all these issues very far past 800,000 points let alone make it to a score this high that would require beating more than one loop of 26 mazes past level 79 (2-3 more loops x 26 mazes is what I estimate).
You can point press birds on level 1 much more than previously thought from what I have found and if the game was done under Demo Mode dip switches it would be very easy to just leech the bonus timer over and over at the end of a maze to set as high a score as you like to add to your Level 79 warp bonus of 780,000 points (pressing player 1+2 buttons at same time resets timer to 9000+).
Also from higher levels you can just warp backwards and play the early easier levels to add to your score with far less risk. In addition to carrying the warp transporter coils forward into the game by avoiding them, you get more chances to warp forwards a couple of levels to the start of the next loop around the 25th level of every loop of 26 if you play level to level from 1 (only if you entered the transporter earlier and came back to the same level to get the transporter out of the way like I do in my playback).
Each of these later extra short warp forward opportunities also allows you to go back to Doodle City Level 0 and then restart at level 1 with your score intact (from level 25, 51 and 77). Then for some reason at level 103 (25th maze of the 4th loop of 26) it stops allowing the short jump forward and lets you warp backwards to any previous level including Doodle City (no warp bonus though).
I think just crossing the 1,000,000 line without point pressing/backwards warps is still possible whether you play level to level from 1 (Factory Default) or warp to level 79 and then play from there (Demo Mode). You just need a no mistake game with favorable enemy spawning to do it. Easier said than done
