The game has a very cool concept of survival.
It has a simple but consistent use with the game jam theme, which was interesting.
The music is great, it combines very well with the shooting show as you advance. (Initially I played without headphones on and so had a big scare at the climax of the first song, but it's great xD)
The sound effects are also great and don't disturb the rhythm of the music.
The later levels was a good variety, even bringing simple changes was really cool.
I just found the power ups without much variety, the game has much greater potential to show, a great combination of new powers will bring a good replay concept to the game.
In the end it was a great game, I hope everyone keeps working well.
