Neon Wings

01. I'm not able to use the crystals to upgrade the level for the skill type... 02. Using either finger control... it starts to drift into spots I don't want it to go which gets my ship destroyed just about always... 03. The Shimmer while defeating waves of numbered rocks and Haptic feel are making it difficult to play the game and it got REAL SLOW almost on the verge of having while going up against the LAST BOSS on Level 7

Originally gave this game 5 Stars but an issue I've encountered is that my upgrades are locked at level 12. For some reason, I can't upgrade the amount of exp or firepower. I just keep seeing this message that says "Reach level 13 to unlock", but my plane has made it to level 66 and I'm not sure what else I need to do here. Still a great game and has addictive gameplay.

filled with lots of simple but interesting abilities. has a bug freezing screen while in game. usually from lots of lighting effects while using multiple upgrades,attack speed, and projectiles. should have settings where lighting effects can be turned off or lowered and also have the option to turn off damage numbers from bullets and projectiles.
