Thanks for playing! Yeah getting the cockpit to feel a little more immersive was a big focus for me, and while the little joysticks are kinda superfluous gameplay wise I like having them in.
I don't know what you're referring to the with the wandering to the right slightly, I haven't noticed that. Were you playing the browser build or downloaded build?
The blue things were power cells powering the energy barrier, they're mentioned in the game page description and some voiceover from HQ in-game, but maybe I need to add better directions. Wouldn't be the first time I explained something poorly in one of my games lol. When you destroy all 3 scattered around the enemy bases it takes down the barrier and you go beyond it to take out the final boss.
