There was just something so eerie about the space invaders sitting there and doing nothing at the beginning. Very creative idea! Maybe you could make it so that you can go back into 2d after going into 3d.

I like how you managed to keep the perspective shift a surprise, it really caught me off guard. Very interesting idea!

Yo, for your first submission this seems actually pretty solid.
It might seem lacking, however if you keep up the work I'm sure you'll be able to surpass yourself in not time.

Nice job! The game is fun and has a cool mechanic. Pretty good for a first submission!

Good job for your first participation, great use of the limitation (Space Invaders for the win ahah)
