My few issues with game I believe need to be solved/fix

I believe they really need to fix mana cost and movement speed. I can see early levels having mana issues but when you get in the 90’s you shouldn’t be worrying about fixing mana issues everytime you level a gem to 18,19,20. You should feel more powerful in the 90’s. You get gem level 18 now you need to fix mana issues, you fix it now you get a 19 well guess what you have to now fix mana issues again. I feel like the whole time no matter what level you got to fix mana issues. Movement speed in end is too slow, we need to get faster or monsters need to get slower especially when you run into deli and monsters have faster speed movement. Also delirium simulacrum what you have to beat for delirium atlas points is a little over powered, needs to be toned down little. But delirium itself is great and don’t need to be touched
