Too bad the game stopped saving my progress. It does irk me that it is a money grabber game but has been possible so far. Lever 14 I think. But I agree with Hyperion65, too many good free td game for this one to warrant any money.
I played this when it first came out. The start that hooks you with a fun but low end Atari look and upgrades to a nice Super Nintendo look. Very fun. I find I come back to replay the game every 6 or 7 months. That's a mark of a great game to me, replay value.
The base of the game is good. Two big problems I see is there is no way to get more fuel without the player putting up some cash. Big fault. If you want cash then make it a paid game. The regen time on the fuel is just insulting. Don't BS it. The start of the game just has you running around with no good explanation of how the weapons work, Fuel, ect. Auto fire, manual fire, rating the weapons should be clearer like DPS. The tutorial does not explain much and needs to be polished. The game seem fun but the the few flaw I have found (more the fuel than anything) just kill the game. I could see this a 5 star game if its fix up a bit. but for now 1 star, I hate be force to pay after the game starts and 1 hour of sitting to refuel for 15 min of play, I have better things to do.
Feel like I'm dating myself, but I will still play X-com every now and then. Nice flash game. The best of this type I have seen. I would love to see another.
