Sweet little game.
I like this, enough to give it a numbers crunch:
- Most unique augments are unfortunately too weak. The starting values are all just so low that you'd get more from a random silver upgrade. I'd argue some actually become downgrades as they dillute the pool with bad upgrades that only even draw even on their investment by the time the game is over.
- Accuracy has a very extreme curve of usefulness. The initial 30% greatly increase DPS, the last 30% barely do anything.
- The legendary accuracy upgrade is gimmicky. The maximum you can get is 45%, and even that is just barely 1.5x a gold upgrade. And even a flat 60% wouldn't be the world due to the diminishing returns on accuracy.
- The legendary attack speed upgrade is gimmicky in the other way. You deal x1.5 damage. Initially the upgrade is worth less than a gold upgrade, but with enough attack speed it's the single best upgrade by far.
- Armor shred - outclassed by Assassin in 3 separate ways: doesn't increase damage for the 1st hit, requires more upgrades, and has no secondary benefit.
- Blue Fire - The scaling is way off. The first few upgrades do barely anything. Going from every other to every flame doubles its damage. Before that upgrade it's literally worse than just picking damage upgrades. Should max out at every 4th or 5th flame but the damage scaling should easily be 10x.
- Multicast - bad feedback, are the flames glitched into each other?
- Magma puddles - initially weak, but cubic scaling. Ignores armor. Scales with size, duration, and damage.
- Freeze - too low chance to be good initially but quickly becomes a monster. The slow becomes 99% with just 8 gold upgrades that also give HP. Absolutely turns you immortal in the lategame. I recommend the slow affect speed as speed / (1 + slow) and the initial chance go up a little bit. Also glitched, as some enemies in the lategame randomly do not seem to get slowed.
- Vampire - Healing for free is already really good. The initial value is actually good, just simply because there is no other healing. Scales absolutely bonkers to turn you immortal. I'd absolutely tune down the scaling, and also offer more alternative healing, e.g. a slow regeneration.
- Lightning, Barrage, Assasin, and Orbits look pretty good, although all of them need to have their base damage improved.
I know doing the numbers balance can be a chore so I hope this helps.
