Wow, solid game you got here! I was a bit worried at the start that it would be way too confusing and opaque due to the 'help' menu that is just a wall of boring text with no visual examples or such, but I was glad to see that the 'help' was just essentially a bonus glossary you can reference for more in-depth technical parts of the game, while Meno does a great job at walking you through the essentials.
Indeed, while the game might seem overwhelming to start, not only does it have a solid step-by-step tutorial through Meno, but the game is also very friendly with having every element of the HUD be hoverable to get tooltips. Due to this impressive design achievement, it didn't take long for me to get comfortable with all of the systems as any question I could possibly have could be answered by simply hovering over it! Want to know what unit another unit will target? Hover over it and see what gets highlighted red! Want to know the range of a unit? Hover over them and see what tiles get bordered! Want to know what the spell or item does? Hover over it! And so on and so forth.
With all that out of the way, I found the game quite fun to build up a party and get them through the dungeon through a combination of setting up formations, giving them all sorts of items to turn them into some crazy cross-class abomination, finding the right time to cast spells to turn the tide, and all sorts of other strategic elements. Very addictive and fun all-around!
In terms of points that bother me:
While the game is quite informative with all sorts of tooltips and icons and such, it's not always showcased in the best way, such as how many icons are so tiny you can barely see them: for example, I didn't notice the icons for how many exp potions you need to level someone up, or the icon above the reroll button indicating you can use a potion as currency for that action.
I couldn't shake the paranoia and fear that the game would screw me over with RNG at some point, like not giving me good balanced party, and I really don't like the idea of sacrificing experience points to reroll, as interesting as that might seem on paper.
Furthermore, I found it incredibly disappointing that there doesn't look to be any sort of save/load or checkpoint system in play as runs can be pretty long and I don't necessarily always have the time to do it all in one sitting.
To add onto that, it was really annoying to have the game always treat me as if I'm starting for the very first time with all the tutorial messages and such: as cute as Meno is, you'd think those would go away on a second run (or at least offer the option to skip).
Overall great stuff!
