It's okay. A little confusing at first, but then I got the hang of it. Nice work.

Nice idea by tapping Letters to charge but its hard to get in. Sadly there is no Audio, but effects ^^.

The start of the game is confusing, but after a few more tries I was able to understand how to play. The hectic multi-tasking gameplay works very well with the jam's theme, and I liked it quite a bit. Adding an easy way to see how much power each action uses (like a little "-10" or something popping up above what's taking power) could make the game a bit easier to play. Great work!

I really like the concept of pressing different keys to generate power! I would of liked to see more keys then just WASDQE (Thats all I ran into)! Also, just as @vikinggames said, the beginning is a little bit confusing and the tutorial isn't entirely clear! Anyways a great submission overall!

Nice little game, it was hard to aim at enemies and press the correct keys, lowering the difficulty might help a bit

Wow, I really like it! The graphics/interface should use some improvements:

- Everything is very grey and dull
- There should be some indication of whether a turret is turned on or off
- You should use Left Button Pressed to shoot. I would often shoot accidentally
- There should be some indication of when energy is being spent. A little red "-10" should appear, slowly fly up and fade out whenever you shoot manually and the same kind of indication should appear when enemies hit you or turrets spend energy. Alternatively, you could include this information in the instructions, because I had to do some experimenting to figure out how much each thing spent.
- The graphics could be prettier, in general. The background doesn't seem to make much sense and the amount of pixelization varies wildly.
- The timer should be in seconds instead of steps :)

I think the key-pressing to generate batteries may be a bit broken, because I mashed all the keys instead of actually looking to see which was the correct one, but I'm not entirely sure my method was faster. Still, it was a lot of fun! It's a simple idea that works really well. I think you should wait a bit more before the enemies start coming, so players get used to the controls. And some sort of difficulty progression would also be nice, as the game is a bit hard (I beat it after a few tries, though).

Interesting game, I like the idea of multitasking, but i couldn't figure out how to generate from the battery. I'd press all the keys but the power in the top left would never go up, so I always lost even after conserving energy by turning the turrets off because eventually i'd just have no power left. I really like the concept of multitasking with limited power though.

Nice little game, it was hard to aim at enemies and press the correct keys, lowering the difficulty might help a bit and everything is grey and dull so maybe add some colour?
Other than that:
Keep it up!

The pressing keys mechanic was interesting but I felt like I was dying way too quickly and without any explanation. A bit more feedback would be handy. Nice work though.

I like the mechanic of press keyboard letters to charge power and the mixture between survival game and tower defence look work great. Nice entry.

The concept behind is really nice and the game mechanic is good too, though it needs more balancing, specially when large swarms start to come.

The graphics are nice, but I didn't like the presentation of the instructions in the beginning of the game, it kinda felt a bit not so organized. :P

If you can balance the waves and gameplay, it's got a pretty nice mechanic to work upon! :D

Good Job there!
