It's functional ad has an enjoyable enough plot but has really poor difficulty balance, it switches from braindead to frustrating with literally 0 inbetween at around when you make it to town, it's hard to tell bullets form backgrounds, enemies start taking cover far more often and even teleporting randomly, to the final boss who even has an attack with no time for anticipation as you just get crushed by it, can't even bomb it. You aren't even safe outside your bubble during a bomb which makes it not very useful for getting out of a tough spot.

Also no, a million shots that just home at you is not level design.
