There's a big amount of work here! I love the arcade feeling of the game and the addition of the shop with the countdown is pretty smart! Though I have to admit that the shop part was a little bit stressful and unpleasant. I like the concept of rushing to get your addons, but there's something that made the experience not so great to me, maybe it's about making the shop a tiny bit smaller? Or making the robot faster?
But overall it's a great game. And congrats on the audio work which is quite amazing!
