A great first game, especially under a tight time constraint! The isometric camera is interesting, and it's nice to see you didn't cop out on some of the more difficult stuff, like animations. I love having your combo meter pay for different attacks as a mechanic.  The movement was backwards from what I expected(W moved me towards the bottom of the screen), it was easy to get stuck in a corner, and the timer is so long that it didn't create any real pressure. It also would have been nice to have some color in the game, even if its just flat solid color materials on some of the walls. When time constrained like this, it is also easy to forgo tutorials, just hoping people will figure it out, or posting it in the description, so I commend you for actually including one!

as the first game you've ever made I am very impressed. the core mechaninc of a combo meter used to pay for abilities on top of the two different weapons getting their own combo is a very fun idea, and they pair together so well. the attacks them selves feel lack luster but for being made in 4 days it's not half bad. I hope to see your future work.
