Ahhh I'm so bad at this game!!! I know it's entirely my own fault, too! I can almost never get past the skeleton room (well I imagine they're skeletons, anyway, it's the third room) and never past the fourth room. I also get impatient in the spider room and end up losing there a lot of the time. I really, really tried my best!
It's fun though, and I super appreciate the auto-fire! I'd appreciate the dash too, but I keep forgetting to use it.
One thing to note, I think it would be helpful if the enemy projectiles were a different color from the player's and also the cursor, sometimes I mistook my own cursor for a lethal attack. That might also be a 'me' thing.
