You'll need some resilience because dead means dead. 8-)
And that's just one of the aspects of this game I love. Nice opponents, sometimes pesty hard to kill. Learn to use what you have in your inventory, especially these seeds are very useful.
I like this game very much!
I played on mobile many hours for several years now and endlessly dying but it is not even annoying!
There is so much to learn and discover in this game that it is by no way boring. Every time you die you have to start again at the beginning and you can try different characters, each has it's pros and cons. Very hard game, I didn't managed to finish it but I find it very fun and clever.
I am not a big gamer but Shattered pixel is one of my best game experience. I like it much more than all AAA games I tried and got bored of.
