Ah, bummer to see this :(
I already made the game quite easier in normal mode through the last updates but I can give you some tips!
It is a RogueLike with kept progression, therefore you can still play in easy mode, amassing resources and upgrading your skill tree before going to normal mode. It is intended to be hard at first, and being more and more easy through your upgrades.
Some characters you'll unlock are better at managing garbage than others. The more you play, the more you'll encounter unlockable characters. Up to one per run!
