Stuck in Not Another Magic Tower Game.

First time i play this game. So far it's pretty good. BUT now i'm stuck!
What do i do?? i've tought of using cheats but that can't be the only way to do it, that would mean you're not supposed to get the ending first-try wich i don't think is a good idea.
As i see it, i was supposed to kill that red monster cherry on the right, but went down and saved instead. Is there any solution???

Nope you softlocked, 0 Blue Keys what were you doing with them I have to ask? I do not mean any offence i just wanna ask.

Here's a guide for the game made by para

I think 2 screens before there was an option between blue and orange, and i went with blue because it was closer to the save (i regretted it even before getting stuck tough, because if i wanted to backtrack to that area i HAD to use the orange anyways, but i had already saved)

In the future, i better use that really cool-looking backup system
Thanks for the tutorial btw.
