Ayy, got to round 24!
Gave 4 stars on everything except for the Audio and the Graphics, due to you using premade assets and on the gameplay due to the massively distracting juice and the dissapearing bullets.
Overall - I really like the game. My main problem with the game is the juice. Damn it's kinda... bad. The screenshaking is EXTREMELY strong - you can literally see the edges of the screen wiggling around like jello whenever you do anything. It's very, very distracting. Also - the enemies have an exploding death animation but they make a grunt rather than an explosion sound when they die? Overall I'd say the juice is the weakest part of the game and does bring the experience down.
Other than that - I realy like the main idea. I went for a attack speed, multi-bullet build while denying my enemies attack speed and bullets; that way I didn't need to spend much energy aiming and cound focus on dodging. And because I didn't buff their bullets it was easy to dodge. That did lead to me having to open all 4 portals and get 3 waves, which was my downfall.
The game is rather buggy, with the dissapearing bullets and enemies getting stuck on the ceiling, but overall, really nice game. Great job'!
