I like the look, feel and theme of this game. It's simplicity in design works well for it.
My issues with it, is theres no feedback to the player that i'm hitting the enemies,
because of that i don't know if the Sun is just an irritation to ignore, or a big bad boss to try and destroy.
There's no consequence (it seems) to just letting the baddies go past to the bottom of the screen. The difficulty level doesn't increase over time. In the end my health (which i figured went up from killing enemies) was just climbing higher and higher until i finally got bored.
I do like the game, but hopefully that feedback will help with future game jam games etc. :)
Well done!
