Well in terms of explosive cum and ghost parade these shouldn't be much harder than usual. With explosive remember it counts for every enemy getting down, so jumping onto bats is instant explosion. It can open nice shortcuts and you should focus on going down fast. Should have some spare snakes as explosions can dig hard to get out holes.
In terms of one hit, rainbow cum and overall minimizing chances to get hit.
- You can judge if enemy will raise from ground by animation. Belly up is already taken down, belly down is still not. Mummies have 2 HP, bunnies I think 3
- Don't throw objects near walls, big chances it will rebound if you miss or even hit enemy will rebound and strike you.
- Carry something (the best is taken down enemy) if you go into unknown. If you get striked by dildo cannon it will plug the enemy you carry instead of you. If enemy is plugged already, it will still save you, but you dildo will fly somewhere further (usually slow and controllable). Even the vase will help in that.
- If you throw enemy into enemy, expect only one will take damage
- You can throw vases and enemies into cannon paths, it will trigger them without you going there.
- Bats always go to your waist level so go back a bit and you can easily jump onto them.
- If all the drops down are blind, maybe there's somewhere place you can shortcut with bomb where you land on visible platform
- Graveyard is a lot easier finish than basement, however in rainbow cum challenge check if you will survive at least 3 doors as you don't get food there. Basement still gives food. I think the last door can put you over the edge, show game over, but it still triggers ending.
- You can destroy the launcher with bomb if it's the only path and you don't have anything to throw to trigger it (basement level can begin like that)
- Avoid clumped enemies, especially when there are 3 or more, they will kick each other.
- Items and enemies can bounce on snakes (even downed ones), so be aware
In One hit you can really focus on just going down, there are no food pickups and usually you will find at least one bomb pickup, so 5-6 bombs should be enough to cut everything you need (well even 3 can be enough). In rainbow cum you need to find few foods, so avoid unnecessary encounters and try to pickup every food (all the food spawns have some safe tactic i can do 100% of time)
