Fun game! The feedback was top-notch, and simple sprites with post-processing always look amazing. I found that after some time I had more fun shooting every bullet through a portal, and then just pushing the bullet towards the enemy with my character, than shooting them directly. The game would've been even better if it got harder and more hectic over time, but as I've read, you had very little time for the mechanics. One nitpick: I think the screen shake was a bit much at times, especially with a lot of projectiles. Once again, well done! :)
