Neat game! I included it in my Game Maker Toolkit’s Game Jam compilation video series, if you’d like to take a look. :)

great idea

This one was my favourite game i have tried in the jam.  Amazing feel, super fun, solid visuals and audio.   Just AMAZING

The simplest of all the games I've tried with a solid look and feel for the theme and gameplay!!

Great mechanic, visuals and feel!! Just gets hard a little bit to fas, other than that really good entry :D

Love the complexity from one button! Got difficult a bit too fast, but the game feel and aesthetics are nice and the design fit the theme well.

That was really cool but tough as nails! Very juice, much game feels, and gameplay was solid with simple but hard-to-master controls! 

Don't understand how the waves work though as it seems you don't have to destroy all enemies. Given that you move around at top speed, would be nice to have a zoomed out view especially when travelling faster as its hard to dodge something offscreen.

A great game you have there ! The visuals and feel are really nailed down and it gives your game a lot of personality. You also have a really good use of the theme. This is one of my favorite game of the jam !

Since I really liked it, here's some things that I feel could make it even better :

There's too many enemies. I ended up not using the deflect offensively at all, but only escaping and defending with it. This is because there was so many projectile I didn't have time to aim for the cool deflects and feel like a badass. Instead, I let the enemies kill themselves while I tried to dodge the projectiles.  Have less enemies but make each of them a real threat.

The Projectiles sometimes didn't deflect where I thought they would. This contributed to the issue about not being offensive enough. I didn't want to be offensive because I didn't feel it was 100% accurate.

As mentioned in the other comments, you could probably unzoom a bit, perhaps even move the camera toward where the player is aiming if the cursor is at the edge of the screen.

Anyway, great job on the game, you did an amazing job !

Really nice visuals! I enjoyed the colors and effects. The game also feels great!

Gameplay !

Great level of polish and an excellent concept. Love it.

This one made me feel super cool. It looks great and plays great! I only wish the camera was zoomed out a bit to make it easier to move around without bumping into off-screen projectiles.

Really difficult but really fun :D
