After struggling in Biome 2 for hours, I beat the boss, Biome 3 AND THAT boss on my first try!
I don't know how common this is, but I am absolutely thrilled at my accomplishment. I struggled for hours in the desert, just dreading every restart because I felt like I made no progress ever. I had only made it to the construction room, where you can choose between 5 things and a health upgrade, plus a reconstructor for 6 ether. Immediately after that room, I would be dead pretty quick because I am just ass with a controller when it comes to shooters.
But something happened and I not only got to the boss, but I beat him - first try! Never seen him before in my life. I was ecstatic. I pushed forward because I felt like I had decent gear and upgrades. Took my sweet time in Biome 3 and was just carefully making my way around the place. I soon found myself in front of the red door and was like "There's no way I am ready for....wait, I am at max efficiency? 15 for now, I guess 30 is locked behind something. Oh well, let's go..." and I jumped into Nemesis' arena - again not knowing a single thing about the fight. HOLY HELL was that crazy. But to my absolute surprise, I beat him. I managed to save myself with the parasite that healed you to green when critical, which 100000% saved my ass at least twice. But man was I absolutely hyped to make such progress with 0 knowledge of the biomes or their bosses. I know this is just act 1 but man, this felt great.
