I thoroughly enjoyed playing your game; it reminded me a lot of the classic Space Invaders. The arcade-style music added a nostalgic touch that I found quite appealing. The artwork was particularly striking, especially the design of the bosses, although it would have been even more impressive if there were more variations in their models.
I did encounter a potential issue while playing—the game seemed to lag whenever the bullets collided with the bosses. Additionally, I noticed that the bosses occasionally took damage without any input from me; I wasn't sure if this was intentional or if it might be related to a timer indicated by the red bar. Furthermore, I accidentally discovered that pressing 'q' closes the application; I'm not sure if this was an intended feature or not.
On a positive note, I found the controls to be very responsive and intuitive, which greatly enhanced the gameplay experience. While the thematic elements were somewhat on the bland side, they still contributed effectively to the overall atmosphere of the game.
Overall, despite encountering a few minor issues, I had a thoroughly enjoyable experience playing your game!
