wow, lots of potential, don't give up working on this and you could have a great game. As of right now you need to polish this, and fix all the balancing issues.
ok the premise is good. but it runs WAY too slow. and the letter you need doesn't come up. Why do they have to be falling anyways? It doesn't add any gameplay element by having them fall, except now I have to wait for the letter to pop up.
the graphics aren't that great. the gameplay is repetitive but fun. Haven't rated it yet cuz I'm still playing but so far so good. Probably is going to need lots of upgrades to keep it fun and fresh.
