I liked there was a separate scaling cost for upgrades and new towers, encouraging use of both.  It wasn't quite clear what the exact difference between the cannons and ballista were apart from fire rate. The projectile "over-kill" as it seemed was confusing as it wasn't explained to me leaving be confused as to whether it was a bug. Despite those confusions it is quite simple to understand and I even did a retry to see if a different strategy worked better. - Devinant

It was enjoyable little tower experience.

It's a well made game, although it would've been cool to see more variety in defenses and attackers.

Cool game. It's unfortunate that there's not that much strategy in this game, but it's a game.
Good job.

Thanks for making it.

nice music choice! 

but game is too ez :p

Nice game, not much variety in the upgrades but solid overall!

A perfectly solid tower defense entry.
