DOSBox at 3000 cycles. There are lot of tightly-timed levels in this run: 8-11, 13, and especially 14 with its crazy triangle jump. Major mistake is at 12, missing the platform at the beginning and self-exploding for a faster repositioning. The acid drops are RNG-based but the PRNG always starts and changes in the same way if you reboot the game, making them consistent if you play consistent.
