Around 1 hour 33 minutes to beat. Check out the no commentary version if you just want to listen to the game. This breaks down what I did, mainly the final boss, as that may prevent many players from finishing the game. Theres a very easy method. The final boss seems extreme without the fast method I found to kill him. It wouldve likely taken some hours to beat otherwise. I didnt see this method anywhere online.
Deaths were edited out from the 6-5 checkpoint and the final boss checkpoint. The rest of the deaths were left in since I made pretty steady progress with the rest of the game. You can see how frequent the checkpoints are. If I edited out all the deaths it would be tedious and not show how the game works. Its short enough anyway with the rest of the deaths left in. The game loops after the final boss.
