Glad you liked the game and thanks for the comprehensive review!
I will now proceed to answer your points:
1. I will look into it, hasn't been reported before, but I think I may know how it happens
2. The main save is replaced by the one you played most recently. Autosaves are created when a update action has happened - like getting a new character, leveling someone up, using an item etc. Also when you go back to main menu, an autosave is made immediately
3. This is a known bug, but it is sadly due to an external addon I use for tooltips, thus not much I can do about it currently, it just works like that. I will someday write my own tooltips so that doesn't happen, but can't say when exactly
4. I will look into this, in general the tutorial hasn't been tested very much so that is to be expected I guess
5. It should presist, just tested it. This might be something related to switching saves, as the settings are kept within saves
6. There are certain skills that can't be used with keys
7. This has been fixed in the developer version so will come with next update
1. Some such inconsistencies have been fixed in the dev version
2. The GUI in general is not at all polished, things like easier understanding of the UI will come as the game matures (I am a single dev after all and not a professional in UI design in the slightest)
3. I was thinking of doing something about that, I may just make it so you are just taken to the crafting menu instead. There will be changes to how the UI in the character screen feels and looks sooner or later as its quite bad right now, thus that will be fixed along with this
4. You just need to drag the slider to the end to do that. It scales based on the maximum amount of levels you can put in.
5. There is in the dev version
6. This will be addressed in the character menu overhaul
7. What do you mean? All enemies should spawn out instantly after the initial darkened screen
8. I wish you could too... Jokes aside, it is not skippable because I kind of rushed its implementation. It is in the dev version
9. You can switch between them in a couple of ways: drag with the mouse (finger if you are on mobile), scroll wheel or keyboard arrows
Yeah the game is pretty easy to beat currently, but stages will get harder as the story progresses and enemy levels rise.
Hope I clarified some of your points and again, I am thankful for the review!
