Very impressive entry!
The graphics all go together very well, the controls feel great (I went with the recommended controls, but I loved having an option!), it's a very good idea and very well executed.
Multitasking driving around while (most-of-the-time) dodging enemies while also exploding enemies feels great. I ended up being defeated by the wave featuring the big one, but I'll definitely be back for more.
Excellent job on this submission!
