This mod is absolutely amazing. It makes playing the non-overhauled version of Terraria pretty hard. However its not perfect, but I'll explain that in a bit.
Movement with this mod is perfect and a lot less linear than before. You can actually dodge the attacks from bosses or enemies, rather than attempting to jump or dash around it. My only real issue is that the falling speed isn't capped so going down to the underworld is jarringly fast, and the momentum you gain while using a gravitation potion is ridiculous, making it useless for much more than finding a sky island, and this issue came to light in the Queen Jellyfish fight from Thorium where her bubbles shoot you to the top of the map, and your absurd falling speed probably despawns the boss once it catches up to you in the sky.
Combat is hit or miss, some changes are okay, others can be annoying. A lot of weapons that had their best quality being auto-fire have been nerfed in this mod (primarily the Murumasa, which is now pretty useless aside from making the Night's Edge) and a lot of other weapons have been made better due to this.
The dodge roll is by far my favorite mechanic from the mod, as it makes combat feel less clunky and annoying. I would highly encourage making this part of an Overhaul Lite or something, for people who only want the most important features, like the combat roll or weapon changes.
All of the other changes are pretty welcome additions that make the game feel just that much more polished. Great mode overall, however it does have a one glaring issue. The alt-tab issues. This makes doing anything else but Terraria basically impossible unless you like playing on windowed mode. If this issue were to be fixed, the mode would be a clear 10/10, entirely worth playing.
However, due to the alt-tab issues I give it a 8/10, wholly worth playing, but its not as perfect as it could be due to one major issue, and the main post detailing things about the mod needs to be updated! It says projectile swords only use their projectile on power attacks but it is quite the contrary, they fire projectiles per swing, and shoot three on power attacks.
Great mod!
