Howdy! After doing some work I've decided to publish my current method for completing the game 100%. This will only be a surface-level overview but I'll elaborate on certain details if I feel they're needed. I'll upload a deeper look at the route once I begin to really master it. As of 3/5/2021, the current strategy is as follows:

Part 1: Flosante The start of the route is very straightforward. To begin, you simply play all the dungeons in order and leave once you've collected everything. Items: Map A, Map A-1, Proximity Mine, Hover, Life Up

Part 1.5: Impact Wave I believe this part could be optional, depending on the player. I find that having Impact Wave as early as possible makes the rest of the game easier. Therefore, after leaving Flosante, take a detour through Planetoids A-1, A-3 and B-4 before (ha) heading into Montoj. Items: Map A-3, Hexa Missiles, Map D-1, Map B-4

Part 2: Montoj This is also pretty linear if you know where to go. Don't bother with the grotto on the right just yet. After defeating Gathervira go back up the mountain and talk to Gonbei. When finding the coins, start by heading west and gathering them in a counter-clockwise direction. Once you return to the east side of the planet, the remaining coins can be acquired in any order, although I believe the grotto should be kept for last. Remember to return to Gonbei before leaving Montoj forever (I messed this up once and ended up earning myself a two-hour Any%). ALSO keep in mind that Jason can't pick up items while he's invulnerable during a counter. If you find yourself in a dungeon with fewer keys than you thought you had, that's probably why. Items: Map B, Map B-1, Map B-3, Map C-1, Shift-up Attacker, Recoil Jump, Key 1 (to Area C), Emblem Kuebiko

Part 2.5: Energy Guard Another optional section. I tank a lot of damage and having Wave is important for completing dungeons quickly, so I take this detour to Planetoid B-3 before moving on. Item: Energy Guard

Part 3: Immigration Ship L-229 No surprises here. I prefer to do the first dungeon at the start of the level although you could probably save it for the end if you wanted. Items: Map C, Map C-2, Burn Spark, Key 2 (to Area D), Key 3 (to Area E)

Part 3.5: Planetoid C-2 You can hit up this planet on your way to Stranga or not. All remaining planetoids are going to be completed during part 8 so it's completely up to you. This is the final optional section. Item: Life Up

Part 4: Stranga Stranga is a little more open in its design but as long as you approach it systematically you won't have to worry about missing anything. I prefer to start at the top and work my way clockwise when gathering the fruit. Use the Seed Carry technique to make the two seed rooms faster. Do Not Forget to talk to Kanna a second time after she gives Eve medicine. You will have to leave and re-enter the room to trigger the Flosante quest. After Leaving Stranga there's a very consistent method for entering all the Area E planetoids first-try. You go through them in descending order. Stranga Items: Map E-1, Map E-2, Map E-3, Drill Smasher, Repulsion Upper, SP Up, Life Up Planetoid Items: [E-1] Map E, Map B-2, Life Up; [E-2] Map C-2; [E-3] Key 4 (to Area F-1)

Part 5: Divido Desert Divido can be pretty confusing. Although we'll cross this very section on our way to Area G, it is important that you pick up all available items on this run. The one item to skip is the Absolute Comet in the dungeon far east. Items: Map F, Map F-1, Map A-2, Key 5 (to Area F-2)

After leaving Divido you'll want to hit up the following planetoids in this order:

• F-1
• C-4
• C-2 This will make the next parts smoother. Items: [F-1] Map D-3; [C-4] Flash Striker, SP Up; [C-2] Life Up

Part 6: Area D Complete the first three Planetoids here on your way to Area F-2. You'll get D-4 later. Remember that you have to complete D-2 to open the portal to F-2 so don't panic if you don't see it yet. Items: [Space] Map D-1; [D-1] Map D-2, Map D-4, SP Up; [D-2] Life Up, Vector Reflector; [D-3] Revol Buster, SP Up

Part 7: Divido Tundra There's an upgrade to the far west that's really easy to miss. I recommend going there first. Take note of the breakable rift on your way to Atom. Be sure to talk to Stein before leaving the planet. Items: Map F-2; Full Accel. Boost, Life Up

Part 8: Errands Now is the time to complete the rest of the planetoids. I recommend the following order:

• F-2 (DarkBlakki at TenjinES found a great way to skip this) [SP Up]
• D-4 [Map D, Life Up]
• A-2 [Accel Charger]
• Flosante [Fruit]
• B-1 [Flash Sphere]
• B-2 [Reactive Comet, Life Up]
• Ship L-229 [Ship Part]
• C-1 [Map C-3, Auto Cluster]
• Stranga [Emblem Eir]
• C-3 [Torch Bomb]
• Divido Tundra [Emblem Atom]

Part 9: Digrawler After getting the emblem from Stein make your way towards the arena in which you originally fought him. You'll come across that rift again but this time you'll break it and continue through the desert. Complete the dungeon there to get the last item before moving on to Digrawler. After defeating him, make your way to the desert's entrance and leave the planet. NOTE: If you happen to die before reaching your first checkpoint, remember to talk to Stein again for the emblem! Items: Absolute Comet, Key 6 (to Area G)

Part 10: Boss Rush Complete the boss rush and enjoy being so over-powered!

Part 11: Good Ending There is nothing to collect until Eve gets MA Andrea. After that, the upgrades are pretty simple, with the only real choice being the last two. I think the lower cave Life Up should be gotten before the Fred one. Items: Life Up (x4)

Congratulations! You've completed a 100% run!
