totally agree, level 3 din't had that issue as it was a tight space, raising the ghost speed and decreasing the amount of attempts needed is a good idea to avoid exploits and keep the difficulty level but it would bring more issues for example with faster ghosts players would have enough time to just wait in a corner while they end their run, also when i was building i tought that a fun gameplay would come from the great amount of ghosts on the screen, i think that the best fix for this issue lies in level design making it so you can't avoid ghosts by just being fast
Btw the 4Th level is the last one
