I enjoyed this quite a lot, but the game started chugging at around 1000 people, getting worse and worse with more people. After 2000, I just had to stop. lol
This is neat! Simple concept with solid execution. I suck at this game and rarely made it past the third wave, I think. But I had fun with what I saw. Apparently even made it to second place on the high score charts as of right now, because of how few people actually submitted scores. lol Good stuff!
You might wanna add that this game is currently only playable if you're in the USA or Canada to this page too. I didn't see it on your website until after I purchased the game.
