An interesting prototype that with more time could have shaped into something really good.
The shifting between shield states to protect against bullets of the same colour is a good starting concept.
More attack patterns other than the orbs just orbiting the core, more polish, actual death and win screens, and it could really shine.
For only 1 hour a day its a good effort, and as I said whilst this is by no means a game it is by all means a prototype that could, given more time and development, become one.
