First I'll go through the general Route and in the second part I'll explain notable glitches and how to do them aswell as useful stuff.
1.General Route
1.1 Death You start off by killing Death at the start, as the title suggests. After you get the kill, wait until you get the souls then leave to the right. Activate the teleporter, kill one of the brain monsters right next to it and go back to the room where you killed Death. Walk into the very first spike you see. This will trigger a cutscene that gets you to the actual beginning of the game while keeping the teleporter unlocked
1.2 Shrine/Prison/Water Head to the right, all the way until you reach the teleporter right next to the elevator. Activate it then head down the elevator.
Navigate your path through the prison area and go for the water area. In the water area, go to the boss, beat it and obtain the gravity switch. Once you got that, go back to the first teleporter in the water area and teleport. Go into the left portal of the shrine.
1.3 Ocarina Head left into the moonlight forest. In the forest you will encounter one teleport on your path to the ocarina. Make sure to activate it, we need it later on. Obtain the ocarina and use it right away. this time teleport with the middle portal of the shrine. The one you activated right next to the elevator.
1.4 Sand Head right and reach the sand area. Navigate through the area and beat the boss. Get the vina glove and teleport out. This time to the moonlight forest. DO NOT LEVEL UP. you need a total of 1500 souls for the minigames.
(Optional)You normally need the torch item to see the hidden blocks. However those blocks are there and can be used while invisible. so if you struggle with the boss in this area, you could go grab the desert gun for additional damage.
1.5 Minigames (Not required but highly recommended) In the moonlight forest, head straight left until you see a puzzle like area. (room with 4 exits and animal in the middle) To beat that you need to move a specific path. there is a book that tells you where to go but that isn't required. Just exit the screens on the following directions and you will get out. Down , Left , Left . Up , Left , Down , Up , Left Keep going left until you reach the minigame area. Get 1st place in the target and the barrel minigame to grab the gun and ring. (You will be level 11 after this and thats how you face the final boss.)
1.6 End Use ocarina and teleport to the overlord castle. The teleport you unlocked at the very beginning by killing Death. beat the Area and the 6 "trials" to unlock the door to the final boss. Do the short plattforming to reach the final boss.
Beat all 3 phases of the final boss.
2.Useful stuff Pausing breaks a lot in this game. :D
2.1 Death Fight Death has 2 phases which he randomly switches between. Scythe in hand and scythe not in hand.
What you are aiming for is the phase where he lets go of the scythe. The attacks are easy to dodge and if he ever tries to switch to the different phase again you can glitch him.
To glitch him, simply pause (about 13 seconds) when he tries to take back his scythe. You will notice through the pause screen that the scythe just falls down below the screen.
2.2 Shrine/Prison/Water We didn't use any teleporter yet so we are still level 1. Good thing we dont have to fight anything in the prison.
If the dogs start waking up you can pause for about half a second during the wake up animation and they will go back to sleep. Then just jump over them.
After beating the water boss, there is a shortcut you can take to go back to the teleporter, it saves like 10 seconds and requires a precise jump.
2.3 Ocarina No glitches here :D
2.4 Sand He can't teleport you out while you pause. Go past the line. pause and wait for his animation to return to normal. Kill him
2.5 Minigames The target minigame is free, nothing to worry about.
The barrel game however basicly relies on luck. There are patterns that make it impossible and I haven't figured out any way to get past it without relying on luck
You can talk to the people while the game is paused. This gives you full control of your character after the conversation ends. This means you can pause before talking to Mario for the rewards and equip the items while the game gets you stuck at the obtain item screen. Not too useful but it does save the time of the menuing
2.6 End Not really anything here that can save you.
The final phase of the final boss can be glitched during his laser beam attack. As far as I know this requires a frame perfect pause, so mashing might be your best way to go.
