Beat the game with a continue, then again (both on hard) with 1.5M points. Then grinded the start of level 5 for the 10k kills, killing my character to force end the run because it doesn't save otherwise until the end of the level.
Did the 2-all on my first try, then spent the rest of the time going for the hitless. Which I did. (For the note: achievements are broken so not going for 100% completion on that aspect)
Game completed at 100%. I was missing like three items when I finished the last level. Luckily they were 2 CDs hidden in the most recondit places possibles of the last levels, and one hat similarly hidden there.
Played the game a bit. Watched a video, then did a full game clear, in 1 hour of ingame gameplay. Then spent the rest of the time doing the challenges for RetroAchievements in level order, like timeouting bosses nmnb and beating stages separately nmnb. I spent a similar-ish time on everything, with the final level being a bit more difficult (and with less restrictions!)
Beat the game on normal, then arcade and with its TLB all in one credit. Thanks, Fire Arrow X ship. (2h 12m) ----------------------------------------------- Grinded the rest of the achievements.
Got a Desperate (hardest difficulty) clear. The game has no continues. It also crashed before I could save the replay. (2h 16m) ------------------------- Cleared the extra on first try then did again a Lunatic 1CC without a crash.
