TL;DR: Great game with polished mechanics that rarely bug out. It is obviously still a beta build but it is still great deal of fun and incredibly addictive. And can be played both seated and standing
Mechanics 4/10
Polishing 8/10
Beginner-friendliness 6/10
Overall 7/10
Now to talk about the gameplay:
It's fantastic. The feeling of flying trough the air at mach speeds feels great and is incredibly addicting and the fact that there isnt any other games that offers gameplay like this makes it even better. The ODM gear is easy to learn but difficult to master and this is great! The lack of a skill tree or any system like it is made up for by you developing your own maneuvers and skills as you use the ODM gear more and more. And most people even slash thier blades in different customised ways. The target of the titans nape is big enough to be realiably hit but small enough so you can't just luck out. And the maps are great for both experienced players and begginers in thier simple complexity. Making them suited for high and low altitude maneuvering.
Now for some things that can imrpove certain things:
Add a system so that you can controll you gas output in exchane for speed for the grapple reel in and stronger boost's with a slider or a percentage bar. Have it so that things like boost controll have to be unlocked by killing titans and give the player a notification when they unlock it. this will encourage people to try it amongst other things. Add a system where you can upgrade things such as blade durability or gas capacity to give people a goal to atcually play the game instead of just slashing titans.
Compliments:
While it was disorienting that you couldn't swing with the ODM gear but instead had to reel in and turn to swing around stuff this sounds like a bad feature but it gives the player alot more controll and ease of positioning up for a good clean hit for the titans nape. The ODM gear feel's incredibly polished and I personally have never expereinced any bugs with it and it feels natural to gain or lose altitude as needed just by using our instincts. And the detail that the grapple line reels out is such a small feature but it allows for alot of move's that would be inpossible without it.
