Thanks for playing our game! The last level was pretty challenging and we did thought of implementing either checkpoints or just split the level. The last level is meant to be the FINAL BOSS level where you have to use what you have known to get through it. Conducting a lot of playtesting, some players just find it rage inducing and find it difficult where they are almost done with the game, they get sent back to the start. Some players find it simple and easier to go through if they generally play 2D platform games. Of course ideally having more levels in between 4 and 5 would be ideal too! I highly recommend playing till the end, for the ending :D Thanks for your feedback and definitely will consider something like checkpoints for a much better user experience.
