Replying to Patashu's This is the only level flash game by jmtb02:
- the game has a barrier that can only be passed after 2 minutes at stage 25
- the remaining levels consists of holding the right button and jumping sometimes
Assuming that the gameplay has been maxed (no other tricks to employ, positions were optimized to reach the level ends as fast as possible), the only possible way to break the record would be using a different platform...
The author of the game had a contest of his own game around 2009, which consisted of completing the game with the minimum number of actions.
The game had a simple way of recording your actions which could be copy pasted and sent so a judge can verify that it's a legitimate way of beating a level.
Someone on the contest forum was able to finish a level 1 action fewer, which seemed impossible when replayed.
Later they figured out that the majority of people were using Windows while this particular user was using Linux.
The floating point error difference between the two platforms led to desync a legitimate strategy for Linux on a Windows machine.
Notes:
- Couldn't find any information about the contest
- Unsure about which particular game was, but the gameplay was very similar to Warpshot.
