I'm having trouble playing due to how incredibly obvious all of the design focuses on bilking players.
If you don't log in for a long time, you never go over 100 energy. You can be gone a week and only have a day's ration of "free" energy to show for it.
It costs energy to do fucking ANYTHING.
- Crafting. Even the earliest shit is half a day's energy.
- Rezzing after death. Exponential(!) scaling on repeat deaths in one run. (Party members can rez you with their hp to avoid energy cost, but...)
- *Note Boss fight design is SNK-ludicrous. Have fun rezzing.
- Every dungeon floor is 1/10 a day's energy allotment.
- Challenge rooms (also often with shit/no drops) cost energy. They're also typically full of train-rape, so have fun rezzing.
- Bonus treasure rooms (often with shit/no drops) cost energy. (This one is not such a big deal.)
Armor appearance is tied to your initially selected color.
There's no ability to preview armor.
What looks okay in the wiki may in fact look like COMPLETE AND UTTER SHIT on your character.
You can't repick any of your colors. Read as, "Did you pick green? Have fun rerolling, even though it looked good on your starter armor, you stupid faggot." They will probably eventually put in an item or NPC to let you repick, but it will probably cost $5, because "fuck you."
The effort:reward ratio scaling sort of sucks. It's fun as a newbie, but the farm and grind get awful before you hit tier 3. You'll start maxing heat out on your equipment before you can afford new stuff (unless you spend time playing the town market, which is boring unless you masturbate to ripping people off, as Three Rings apparently now does—also, it has no auction house). This results in a crushing sense of stagnation.
Also, it's insulting having to pay 200 crowns to access tier 2. (It's not 100% consistent, but it's incurred the VAST majority of the time, and I have no idea what causes the fee to appear and disappear).
The whole experience has soured me on microtransactions in a pretty serious way. This sucks, because the combat is generally pretty fun, despite its repetitiveness.
