Thanks a ton for taking the time to play my game, and doubly so for leaving feedback! Agree that the movement was probably the best part. The funny thing is, the code behind it is basically a "v = v + a * delta_time" while approaching the goal velocity, from what I remember, with a different velocity for when the player is slowing down. And thanks for finding the issue with the projectiles going through the walls - I knew I was forgetting something, but by the time I got to the submission deadline, my mind had left me.
Interesting to hear your take on the meters. I had originally planned to add limits in, then dropped them in favor of making the game shorter and simpler. Glad to hear that you enjoyed it more that way. 🙂
