Prowler is awesome against the Goliath. So, so good. In fact, I'd say the Prowler is the Goliath's main counter, and when I lasted ~15min at #1 in a Goliath, it was a skilled Prowler that finally started annoying me, made me start missing my deflects, and knocked me off my balance. I was thinking the Goliath is unnecessarily OP, but the Prowler handles it. (Smart Prowler pilots: go stalk Goliaths.) Might OP the Prowler, but making it shoot a spread like the Tornado might turn the Prowler into basically an instant-backstab Rogue. Now that I've typed that, yeah, that'd be OP, don't do that.
This game is heavily influenced by Subspace/Continuum, and it's fairly obvious. I could even tell which ship mapped to which fighter in this, and I appreciated how well my skill transferred. My main annoyance was that score drop. I maintained about a 5:1 KD across 500 kills and regularly flopped from #1 to #25 to #2 to #30, because the score you lose on death is a little imbalanced. A few deaths in a row and you can lose 10-15 places, which seems a little rapid. Maybe knock a little off that multiplier on death, but leave the killer's score gain alone? The only way to stay near the top is not die, which makes sense since it's called a bounty, I suppose. Still rough.
Other random feedback to the author: Inferno needs a buff. That speed penalty hurts and is a pretty rapid way to die -- I noticed I was avoiding it as I played. Most of the power-ups and abilities could stand to last quite a bit longer, too. And spawners could really use a lockout on shooting for the same duration as their protective shield; you can spawn in, immediately press spacebar, and probably get a kill on a surprised person who happened to float through where you pop up with no chance to avoid.
Great game, though, I didn't expect to get sucked into a browser game for three hours. I'll be playing it again.
Tip I didn't realize until a long way in: 1, 2, 3, 4 map to upgrades. I was the idiot using the mouse.
