This is actually really, really cool. The only things I'd like to see are some sort of minimap/radar for while you're in space, and the space flight/landing feels a little wonky right now. HOWEVER--the whole concept of the game is pretty neat and executed well! I'd love to see another version with structures on different planets to upgrade, bigger threats, and a bigger map (similar to johsonq's suggestion). I feel like this might take away from some of the charm though. You should start making a sequel!
One last thing--lose the Portal references already :P Still a 5/5 for awesomeness and much better than a load of other games on this site.
It's an alright start, but only one map is kinda boring. Make it a little bigger, a bit more detailed, and with more enemies. Maybe more weapons as well?
But a good start for your first game.
Wouldn't this need the API if badges were to be added?
I agree with what others have been saying...it's ok, but the "base defense" idea seems a bit poorly implemented. Plus, although it's "more realistic", I don't like how I can't see my shot lines in this one. It makes it a bit harder to aim :P
It'd be much better if the spells you deflected could hurt the enemies as well. Plus, I think the spell recharge times should be a bit lower. Other than that you have the start of an alright game.
Really really good job! You can tell there was a lot of time spent on it. However, I'm not quite sure why the gun is so wildly inaccurate until you put a bunch of points into it.
Lots of fun! A couple things could make it better, that have already been said. I especially agree about adding in power ups/upgrades? Maybe expand it so you can buy fours and more? That was an unfortunate rhyme...
Thanks so much for moving up the difficutly on the hard badge...now it looks like I might actually go through the trouble for it. There was no way that was only worth 30 points.
