I spent way too much time on this. Trying to get a max score is just so complicated (Damdee).
At first i was trying to get as far as possible but alas that is not the strategy, as the score seems to reset at the beginning of each round, you want to die as close to the end as possible of the furthest round you can get to.
I got almost 800 points in one run, but had only 1 hp for the next round, and it gave me only ~300 or so.
At first this point system frustrated me as i had a good run but scored so low, but then it opened up a whole new strategy for me where i deliberately didn't buy some upgrades just to take more damage so i die at the right time. Unfortunately there was too much RNG and after spending hours getting the perfect run.. my very first one was the best hah - (i might still give it a few more hours to hit the god run :D )
Out of all the games i played this the longest, al because of the leaderboard
