Graphics and sound are cute - but, for the love of Pete, a PARKING SIMULATION?! Geez, how lifeless can a gamer be to want a freaking parking simulator?! And as for those who commented on how unrealistic it is - you seriously need to take out loan to rent a life.
Not bad, but it's not finished. 1) Toss lives and let players buy ships in lieu of life. 2) Upgrades, other than weapons, don't seem to impact game play much or at all. Why use them then? 3) Drops are very stingy, should be at least two or three per wave since they last so little and you move oh so slowly. Invincible? Sure, for about two seconds. Bah!
Just what I was waiting for. Another, "You are locked in one room for no apparent reason - now escape!" game. Just what we needed to pass the time 'till summer.
I like the idea, nifty development of defense game. But - it's not finished. Make it more intuitive to change weapons, explain how to use upgrades and explain what they do. Also, the road doesn't have to be straight, have it weave - keep it interesting.
