Crystal Defense

Couldn't figure out what to do at the start, but managed to get a hang of it by just clicking around.

You should definitely tell people the controls at least on your game page, or people will have big problems playing the game.

Aside from that, to get more ratings and feedback, you should rate and give feedback to other people's games, Your game will show up on other people's home pages if you do so, that's how the Ludum Dare algorithm is set up.

Neat. The initial buildup is fun but the game quickly spirals in your favor and the difficulty never ramps up to compensate.

It's funny how similar our concepts are. I enjoyed playing this one but I felt very invincible after a few summons. Good job though!

Similarly had no idea how to control / what to do at first. Worked it out tho' and then had some fun defending for a little bit.
