This was fantastic! The graphics and sound were great, it had a good story, and there was varied gameplay. The shmup part by far took me the longest. I was unable to figure out for a while whether I was supposed to kill everything or just survive. I actually figured out the ships' patterns well enough to be able to avoid them (almost) completely, and there was a run where I was doing that fro what must have been several minutes before I finally died. Then I tried shooting them more and I was able to get to the boss super quickly. XD I died over and over and over again, both in this part and the wrecked ship sections, but I continued on becuase this game was so well done I couldn't not finish it.
The wrecked ship sections did have a lot of obstacles everywhere though, and it seemed like the only way to get through was to move fast and let yourself get hit a lot. And if you died while getting hit, the hit sound effect would play over and over again. Like someone else said, I too would die and spawn with debris right next to me. Also I don't know why but the sound of the steam was the most nerve-wracking thing ever.
The only issue I see with this one is some minor spelling and grammar errors (missing words, stuff like that). But this was really polished and well-made! Excellent work!
