With Ordinary Archer, Scout, and Flinn skills, it seems that they only activate about 1/2 the time I try to use them. This seems to happen regardless of whether I use the mouse button or keyboard shortcut to activate them. again, it's unclear if this is a defect or a feature.
When I try to do a Boost costing 4 with 4 of the appropriate item, I cannot do the boost. I do not know why. If I have 6, I can (and it still costs 4). I don't know if this is a defect or intended. Example: Ordinary Scout Defense from 0->1.
At least for me, this could use a lot more help. It is very unclear how various items, materials, scrolls and/or runes are used. It looks like colors are important, but most of the color coding is not explained. It looks like multiples of some items may be needed for some items to be effective, but others are effective at 1 item, and it's not clear why one would want more than one.
(-)The scroll (Red, Blue, Yellow) is treated as equipment. It's similar, like head, body and leg equipment slot.
(-)The runes (3 slot ) are like accessories, but their effect is stacked in party squad ( up to 9 characters ),
The effect can be seen in "Active Runes".
(-)Consumable items and materials are basic standard items, some can be converted into others.
@nono_boulot - Passive characters only count a percentage for the swarm - 20% with Proof of Rebirth 1, 40% with Proof of Rebirth 2, and 60% with Proof of Rebirth 3. I do not think I completed a 150 until after my first World Ascension 1 (after which it can be /much/ easier).
I think of it an an idle game, since you can gain the resource Nitro Booster when logged out. That said, it is less idly and more active than a number of idle games.
@R2dB6q - the game is in active development, or at least it's been updated multiple times in the last week. That said, I have no idea how frequently (or if at all) they plan to update the version on Kongregate.
@FrostPaladin - The pet Purple Fox along with Advanced Auto Disassembling Equipment from QoL4 helps with inventory management a lot, from my recollection. As another note, since you can disenchant and re-enchant items, nothing is /unique/ that I'm aware of - though things can be difficult/expensive to make. The main issue I had early-game is realizing that the vast majority of equipment is junk, save for how it helps with quests.
As for your first point, the point of Nitro is to compensate for time offline. Note that without doing enough quests and/or getting Nitro Cap Expansion, the cap will be low. This speaks to your third point as well - I don't think the designer really worries about what happens when the game is in the background. In their minds, the game is at the forefront or closed.
For data: I killed Florzporb between days 9 and 10 using a Wizard LV 100 with a LV 24 Fire Brooch a LV 30 cloth shoes and other mostly ignorable equipment, Staff Attack LV 100, Fire Bolt LV 104, Double Thunder Bolt LV 30. Warrior LV 97 and Angel LV 137 had both rebirth 1ed at least twice. Potion used: LV 13 Basic Elixir of Brains.
@faezzi As for things you /could/ be missing, Area Mission Milestones, Lab Upgrades and Dictionary come to mind as possibilities. Also whatever the next thing is to unlock on the Guild is possible, depending on your guild level. There is also quite a bit of stuff locked behind pets (such as much of the mid-later Guild levels) that may not be obvious at first.
@faezzi - It took me about a month to get through the tutorial, the first time. Simplest way to kill Florzporb is to get more damage. Rebirth 1 and Rebirth 2 should improve your long-term damage by a lot.
The other approach (assuming you are doing /any/ damage) is to avoid all the attacks. Enough extra movement speed should allow you to get close enough for attacking, then dodge out of the way of any of their attacks. This can take a while. Also, you'll need enough defense or offense to deal with any of the smaller slimes with distance attacks (my recollection is that they come out below 20 or 40% of Florzporb's health). Alternatively, you could be very lucky.
@Tuberski - the simple answer is to finish the tutorial (under Quest - Global - any named Tutorial X:). You'll need at least 5 WA points, and you may want to be prepared to complete accomplishments shortly after performing the WA (for WA accomplishment points). Are you stuck at any particular step?
I found numbers on SPD. Around 500, it's about a 4% improvement. This is difficult to get before a solid T2 rebirth. Personally, my recollection is that I pretty much ignored SPD until I was doing automatic T2 rebirths and the occasional manual T3 rebirth.
@incentive1 - I assume you're referring to SPD (which is impacted by Agility). You may not have a high enough SPD to have a noticeable impact on casting time, yet.
