Hey guys! I greatly appreciate the good reviews & I'm glad you are enjoying the game :-)
I noticed some were having trouble using the specials, so I added a label that says "Spacebar to use" (or whatever the special key is) on purchases that require activation.
I also added a pop-up message if you don't have enough energy to use a special (like the booster, which requires full energy).
Controls tip: you don't have to hold down the accelerate button if you are already going at full speed in the direction you want. You can let go, look around and shoot in different directions. You'll continue going straight until you accelerate elsewhere!
I do have another random event coming in development, stay tuned!
