Really addictive game, good job. The vibes remind me of Doom and that's probably not coincidental. :D
I must say I didn't really understand how nails work and when they replenish, and I even had a bug where they constantly switched between 0 and 10 on a whim. It also gets a bit annoying when an enemy spawns right on your path (I guess RNG).
But! This was highly enjoyable. I especially like how the projectiles have travel time. :)
Great entry!
