One more AM2R Hard randomizer - Seed 3605913935.
Finally got a mediocre temple 1 - Ice Beam+Spring Ball+3 Power Bombs. Temple 2 was a little more helpful. Spazer is whatever, but Bombs were laying around, and early finally. I IBJ'd (Infinite Bomb Jump) up the right wall of temple 2 to find Gravity Suit (before Varia for the third seed in a row).
I also checked the spike-filled floor of a side room in the main shaft - this one was a little tricky to IBJ because, in AM2R, spike damage propels you diagonally away from the damage source, and you need to be fairly in line on the x-axis with your bombs to not also be shot to the side. I needed to spring ball up, lay a bomb, touch the spikes again, and spring ball up again to lay another bomb and to lie on the first one too as it detonated to start the IBJ sequence, all within the timeframe of a single set of i-frames. Tricky, but I worked it out (and one of... very few situations Spring Ball is useful, now that I think about it). The room had Screw Attack too!
More IBJing above Ancient Guardian's arena where I found Hi-Jump. Wave Beam was behind the Screw Attack blocks connecting the shortcut between temple 2 and 4.
Tower was a surprise on this run. Plasma Beam was, fortuitously, the single upgrade inside the gauntlet before Tester and the boss was guarding Space Jump.
Speed Booster was where Screw Attack would normally be in temple 5, which I decided to check out first as temple 3 is more reliant on Speed Booster to hit everything. Nothing terribly important in temple 3 ultimately.
Final time for 100% was a much lower 2:21:32. My only complaint with this seed is how late-placed most of the Super Missiles were. I went temple 1->2->4->5->3, and my first/single Super was in temple 2 and I found... 2 more in temple 4? and that was it until temple 3 iirc. I wanted to delay more Gamma and Zeta kills than my route allowed.
