For some reason the in-game achievements don't work. I'm in Kenya now and still all achievements are grey. After a restart the achievements still weren't rewarded. Perhaps the dev can take a look at this if more people got this problem?
Not bad. You might want to adjust the shop screen (that pops up when you click the orb in the middle), it shows up on the path, I can't see my enemies anymore.
And you might want a start button for at least the first wave, so players have time to inspect the shop and controls and make up their mind about what to buy before the enemy shows up. 3/5, you're in favor because there were so many sh*t games uploaded today, I'm glad to see one where someone put some serious effort in.
Love it, another good logic game coming from your hands.
But I can't help being disappointed that you do nothing with your fan's comments, like the hundreds of people who upvoted comments about a next button. You reply on the comments that compliment you, but you ignore every form of critic it seems, while it is such constructive criticism, with some little tweaks you can really change your game for the better. It is good, now go make it awesome! 4/5
