342,970 - round 5
Alright, I cleared round 4 on one credit! After that, I dumped two credits in the middle of round 5, two credits in the middle of round 6, and two credits on the round 6 boss.
My deaths were:
-During the fish part on round 2, when the last rocket is going upward. That always catches me off-guard. It moves faster upward than I expect.
-During the crushing hallway on round 3. I tried rushing it to get through before the worm could do anything.
-On a diagonal shooter in round 4.
No deaths to Amazo, luckily enough! I hear he gets easier if you have at least one death going into the fight.
