In the second tutorial stage, if you hit the "M+" button before the tutorial prompts you to, the tutorial script gets stuck there and you can't start the level.
It's pretty fun, but I think it could have been enhanced by the ability to strike your own towers for some temporary benefit. That would have made the game a bit more strategic beyond tower placement, which can be the exact same on every map.
The hidden powers and fog of war definitely add a lot to the challenge! But it gets a lot easier once you realize the same few basic strategies can conquer the enemy every time.
For some reason, the warriors don't like my custom weapons, like my Mushy Basketball Mohawk Mace, Super Crooked Scythe, or One-Sided Double Headed Axe. Oh, well. At least I get a huge pile of gems for crafting them expediently.
I wish the parachute was a toggle, as in, press the button once to activate, then again to deactivate. Or that the drop down key would deactivate the parachute. Holding the parachute key down the whole time you're floating while also moving around is cumbersome.
The varied missions and achievements really separate this game from other games in the same genre. I didn't feel like I was always doing the exact same thing over and over again because some missions require different strategies from each other.
I found a bug. If you are dying from some form of persistent damage, for me it was ambient environmental heat, and you go into your inventory to repair yourself, you will survive your health falling below zero. However, a message will still appear that you died and you'll be engulfed in flames. That effect persists until you travel to a new planet.
This game was fun until one of the later levels where a small clump of enemies shred away my fully upgraded walls in a matter of seconds. It's not worth it to me to grind until I find new walls and then grind again for money to upgrade them.
It would have been nice if you had to actively activate the rune stones instead of just running over them. That promotes a little strategy of checking to see where the nearby mobs are instead of accidentally touching a rune stone and then hoping that the direction you panic in will have some mobs.
