Thanks for the feedback so far everyone!
Yes, I agree, sfx would have really helped a lot. We totally ran out of time before we could implement some of the finer polish for the game that we've had in past games. We are currently toying with different mechanics and improving the code in various ways to give us a lot more flexibility with the engine in the future.
The whole scene is actually 3D despite how it looks. the bullets are all just billboards and the player models are full 3D objects. They were modeled with fairly realistic proportions (if you check out any of @holo's work on Twitter, you'll note he's pretty good at modeling that sort of thing) so it ended up being difficult to see any of the detail in the models. In the future, we will probably have moe stylized models that better show off their features, and more interesting shaders and lighting too.
In the current build of the game, we have dodging remove one of your shields. This totally sucks! But I feel like if we remove it, that might change the game abit too much to qualify in LD, so we left that in. In a futurre release, movement speed may be increased and dodging will have no penalty unless you take a hit while dodging (same as how shielding only decreases when it takes a bullet).
I have been trying to get to everyone's games who have rated ours, so if you leave a comment, I'll play your game!
