At first I was like, when am I getting my new parts? Lol. I don’t have a mouse, so playing on the trackpad was less fun than I think imagined. Also, no middle button for me :-(. It’s a simple game loop that most people can jump in and have fun, the arcade vibe.
I had a few issues with it. The sfx is pretty repetitive, did you vary the pitch? I think that’ll help me feel like I’m not hearing the same thing over and over again. The game could use some transitions between waves. As soon as you start a wave there’s an onslaught of bullets raining down on you. I was like “what the hell?” the first time I tried it lol. After I finish a wave, maybe small screen transition and a countdown would help. It’s way too immediate for a new wave.
But I like the simple fun, and use of the theme! Keep it up!
