Thanks very much for trying out my game. This is my first ever game jam, and you are the first person who is playing my game whom I didn't ask to play directly...
Did you found that the Z key was used for something, two of my friends whom I asked for play testing didn't.
And there was I bug in the Aura, that when Aura is totally finished, it won't replenish in certain scenarios, and you are stuck in the aura and you can't jump, forever... (didn't you encountered it ???)
I just fixed and uploaded it though (v1.0.2)
Tried your game too, and the first battle is too complicated and difficult, as you said. But overall the game and further gameplay is a fun. I voted your game too.
And for your query on the sound of the game, the truth is that I was unable to compose songs for the game (I didn't make any songs ever). I asked some musicians here, but in the last few days, and they said it's too late. Then I decided to make the plot somewhere in space (and hence the gravity is too weak too). But all the art was made by me, and I made and animated the Main Character and the Bugs, all by myself, for the first time.
Thanks again.
