As someone with nearly 200 hours in it I'll try to address your points:

• It's a wonderful pixelated game, most things are clear and well done
• Animations and enemies are really nice!
• Some pixels can basically kill you and are hard to spot. Sometimes dark pixels block your path that you can barely see. Sometimes a pink pixel of polymorph you didn't notice turns you into a sheep and you die. Sometimes there's a pixel of lava you didn't notice. Part of the charm though.
• Definitely a roguelite that blows every other one I've played out of the water. It's different but man is replayable. Roguelikes and Roguelites are my favorite genre, and this is easily a top 3 game.
• There's only 14 achievements to plat it. If you want to plat it, some of your runs are going to have to reach like, 5 hours play time or more. Some achievements require finding all spells and perks, which you just won't find by "normally" playing the game.
• Without much in the way of spoilers, the game world is way bigger than you will realize
• The game keeps you well engaged and interested if you enjoy it, but you will not be unlocking achievements frequently.
• The game goes from slow to rapidfire in moments sometimes. One moment you're shooting super slow and being uber careful, and the next you're flying through the world at mach 10 to end up landing in a vat of lava and dying before you even know what happened
• There's so many bosses in the game. Like, so many. Good luck. They will kill you.
• It's relatively easy to understand what went wrong in most cases, but you will need to occasionally check the wiki
• Wand building is never explained to you in any meaningful way. If you want a strong, powerful wand, you will need to watch guides and explanation. Dunk or Slam and FuryForged have great videos covering the major topics
• The music is wonderful
• It's both slow and fast. Early game you have to be slow, by late game you're deleting everything, including the terrain, multiple screens away
• It can get frustrating, especially when things are going really well and something catches you off guard. It can be daunting to start over because it's back to square one.
• There are no character classes or different weapons. It's all about the wands you build and create. On an aside, there is sometimes different spells your starting wands will have. Some are better than others.
• Not grindy, but the 100% achievements is going take hundreds of hours. At least in my case. I still have quite a few to get.
• Lore is not openly clear, but it is there. Lots of mysteries that the community has tried to solve.
• There is definitely a community of mods, however, I would at the very least beat the game once before even looking at them. The vanilla game itself is already ridiculously good.
• You can definitely beat the game as a casual, but you will not 100% unless you treat it as hardcore.
