How does your game fit the theme?
In the popular arcade game "Space Invaders", you play as the spaceship shooting aliens. However, the roles are reversed are you control the group of aliens. You can change what directions to go AND choose which alien should shoot.

I like the idea behind this game, and I definitely see the potential. Changing from controlling a single fighter against a swarm, to controlling a swarm against a single enemy, definitely has some interesting implications. I do have some ideas for possible improvements:

The many to one dynamic feels like it should be more of a boss fight. Currently I'm just shooting single attacks at the time, which kind of downplays the swarm.
The movement makes me feel disconnected from the action. I would suggest allowing more freedom of movement. When playing I find myself just waiting for bars all the time.
If you're feeling extra creative, you could fully revamp the movement logic. For example, you could move around smaller groups of aliens for strategic positioning. Although this is clearly outside of the scope of a 48H jam. Also, it will make it more distinct from the source inspiration, which you may or may not want to do due to personal preference.
I like the idea if the aliens would just keep coming, maybe depending on how much damage you can do. This would invoke the feeling that you're overwhelming earth, which I feel fits with the theme of both the jam and Space Invaders.

Overall I think you made a good attempt!

Thanks!

We were actually considering if we should remove the movement cooldown while playtesting, but we sticked to how aliens would move in the original Space Invaders (i.e. the less aliens there are, the less cooldown they move). Maybe we should've have more people playtesting with seperate movement versions to see the feedback?
Do you mean allowing aliens to have separate shooting timers instead of 1 global timer? Or selecting multiple aliens to shoot at the same time using the global timer?

I think we were a bit messy during the last few hours of the jam so we didn't think of gameplay that would compliment the goal of the game (overwhelming earth). Next year we'll try to compliment the intended "feeling" of the game more! Thanks for all the suggestions.

Sorry for the late response, there are a lot of things happening in my life and it's difficult to find the time to sit down for things like this. Now, let's address your points:

This type of problem is very difficult, and not one you can consistently solve within 48 hours. However, I do have some experience in creating a game based on an arcade classic. Games are build around gameplay loops, and this is even more true for old arcade games which don't have much room to build complex dynamics. As a result, by changing just one element of the gameplay, you'll have to rethink all the decisions that were made for the original. In the case of space invaders, the behavior of the aliens are optimized for simple AI. So, to create challenge, they created an entire swarm. Although I don't think this fits well if you give the player control over that swarm. So I'd say in this case it would've been better to rethink what the swarm really means, and if you can change the movement to be more appropriate for player control. Just to clarify, I'm 100% talking with hindsight here. I'm not sure if I would have caught this soon enough if I were to actually develop the game.

Both would address the feedback. Although I should mention that there are a lot of things you could do address this. You could determine which alien shoots purely by some algorithm, for example. Another perspective to take is that each alien is more or less equally powerful, but you can only utilize one at the time. So you don't really lose any value when a single alien gets killed.

Thanks for taking the feedback well, and I with you the best of luck for your next jam!

Thanks for the kind words! Can I ask what extra feature swe should've added that would've made the game more unique? Like more visual effects?

I am not necessarily sure, it could maybe use some fine editing for perfection. :)
