Interesting concept for sure, but it had some issues.
Controlling both at the same time, even though you can only see one, was really really REALLY confusing and annoying. I would suggest to make the game splitscreen. Otherwise the controls were really smooth, which i liked.
The graphics were really good for the most part. I really love the 3d look(as most games in these Jams are 2d) and looked overall decent as well. Only it was at times difficult to tell what is what. Especially the lasers. Look into...what was it called? Post Processing Effects! It helped me a TON when i learned about it. You know 'emission shaders', that are suppose to make something look like it emits light(like lasers), but in the end it simply makes it so that it doesn't have any shadows? Well, Post Processing Effects help with that! It was a game changer when i started using them.
