I got up to Wave 78, but none of the Wave achievements unlocked after I exited the game. Is there a specific trigger for these achievements?

Is there a developer out there? This game has to be improved I am pretty sure it is unbalanced. Well a game exists to have fun but this sucks, because it could be a good game ( I do not want to insult you). Is there any way to change data to make this game easier for me? maybe more health or slow enemies? I am not a total noob at typing but this game seems to be broken ...

Why is it that you can only level up your castle twice. This game needs more content... Maybe I'm asking too much for a $1 game, but still

Tried the game out and was able to survive a few waves before tried to upgrade and then wasn't able to finish off the 20 runners and 4 camel riders with 4-5 letters each. Is there a hotkey for the special abilities, is repair automatic, and what exactly does each of them do? Like when is a good time to do a bomb or upgrade? Are there any special abilities other than upgrade, repair, and bomb?...
