Awesome run.
now for your next trick, one that does allow deaths, but allows collecting each coin once, with each 15 coin block counted as either 16 or 12, depending on if you can get close enough for all 16.
for this route you would have to die a number of times to collect coins from alternate paths without recollecting coins you already got.
ideally, all secret rooms, and all not secret room coins would be collected, but that may or may not be possible. is it?
route required i think.
1-1 go to passage coinless collect all in passage and die from timeout to go back to start, then collect all non passage coins.
2-1 a death from timeout is not required if you do coinheaven first, because the skipped passage should be after the checkpoint
3-1 because the checkpoint is before coin heaven, you do not need to die by time out. you can die as soon as you collect the three that you have to skip if you take coin heaven, than take coin heaven the second time.
4-1 the branch is after the checkpoint, so again you can just die once by pit
4-2 a death by timeout in the warp zone is required. the passage skips zero coin.
5-2 coin heaven skips no coins, but the water passage skips coin heaven, so you must die in the water passage. this may be possible without timeout from the monsters there.
6-2 this is annoying. coin heaven and water passage are before checkpoint, and water passages skips coin heaven, and both come out after the checkpoint. i believe two deaths to be required on this level. one in water passage by timeout, and then one after taking coin heaven to revert to checkpoint to collect passage 3. Passage one should pose no issues, as you should be able to collect the coins past it, then backtrack to the pipe.
i believe 8 deaths are required, three of which must be from time out. can anyone imprive this?
