I didn't have any crashing levels, luckily, but I did run into other issues, such as HP drain, double hits, and a general lack of feedback when interactions were happening. There's a lot going on all at once and the gravity folders and homing missiles are extremely hard to dodge. Those missiles will 180 and come straight for you.
I like the concept of the game - avoid distractions and start developing - and the music definitely gets the blood pumping. Good job ʕ•ᴥ•ʔ
