Any tips for helping me beat more demons?

I have 44% on against the god I am playing on mobile and my hardest is a medium demon called geometry quest 

Use practice mode

I know that is logical but I can beat the level In practice mode but when I try it in normal mode I just die In the most stupid way

Use start positions

Practice the level starting from the end and work your way backwards

Etc

practice is the best way

oOoOO thx drummer GD I'll try but I also need uldm bc my phone is sooo bad I actually need this option so I will try doing something

i lwk just play demons that are good. Usually I aim for legendary and mythics, as the three insane demons ive beat are all legendaries/mythics

Copy the level and use startpositions to get runs. Try to complete the level using various runs then get better and better runs until you beat the level.

Or just buff it and beat it then the level will seem easy to you. (Joke)
