Movement feels smooth, I like it. Otherwise, some health indicator would be nice. And if mouse is used anyway, why not bind shooting to it too, instead of space bar.

PSA: Your Mac build is busted. Throws the typical "This app cannot be opened" error that a lot of >=5.4 Unity games seem to be suffering from.

Will have a look at it on PC tomorrowish.

There is a lot missing, but I can totally relate to that, when there just isn't enough time.

So I try to give you some input for a possible "complete" version (as we know, no game is ever truly complete).

Sometimes enemies spawned directly on top of me and most of the time enemies just got stuck in a corner and weren't really a threat.
It felt strange that the bullets fly so slow compared to your movespeed, it felt more like I was shooting mines. (But fitting if one of the weapons is going to be a mine launcher :wink: )
Don't forget to add more feedback to shooting and taking damage.
Also add everything that @sunnray said to that.

Not a bad proof of concept; finally got around to playing on my PC.

The shooting feels oddly fun, even if it lacks some punchiness, and the movement is swishy and nice. With some small tweaks to add some amount of the theme, and some polish (e.g, a healthbar, some decent SFX and BGM, that sort of thing), this would actually be a pretty solid wave-based shooter.

Pretty solid gameplay, the pace of combat feels good. Some sort of indicator for the direction your ship is facing, plus any basic sound effects, would be a huge help here. Keep it up!

Feels more like a basic twin-stick shooter prototype. Nice controls and level but I can't associate it with current ludum theme.

I really liked the smooth movements it's such a shame you couldn't finish the game properly. Even though you would have done a lot more, here are to me some of the principal things that are missing: signs and feedbacks. You figure out pretty easely what your objective is but the ship's direction is a bit tricky to find and this makes shooting or aiming complicated. Good luck!

Missing some key gameplay elements here at the moment (e.g. a game over state would add a lot to this) but gameplay feels promising and the minimalist graphics work well.

You've got a good foundation here to build on. I didn't feel like I was ever in real danger though because the enemies don't spawn that quickly and I am much faster than them. It would be nice if shoot was on left-click too.

This game definitely needs polishing:
- it lacks objectives; pickups, enemies, levels, etc,
- movement is nice, but making player shoot with mouse would be great, because mouse is still used, so I do not see a reason to shoot with space, not by clicking,
- it gets monotonous very fast,
- health bar or changing colour of the player would make it easier to know how much health have player,

Except that it feels like prototype for something fun.

Well, I know it's an incomplete game and all, but eh, no harm in doing a proper review for the hell of it, aye?

Pretty basic shooter, it seems, with enemies that follow you and obstacles to move around. Enemies are simple, but nothing wrong with that. Shooting was a tad weird; not sure why you opted to use Space as your shoot button instead of LMB when the mouse already aims. Also, it seems that the further away the mouse is from the player, the faster the bullets travel... Inversely, I can make bullets that barely move and act as mines~ It's a shame you didn't have time to incorporate the theme in properly into the game, but otherwise, it's a functioning prototype. Wonder what you'll do with this in the future...

I liked slow shooting mechanic.

A health bar and indicator of what direction you are facing would be really useful but the art style is simple and clean and the movement felt good. The game just needs a bit more work.

Good start! I like the style, reminds me of those old cuberunner games. I don't have much to add to what everyone else has said. My main suggestions:
+ Make the controls consistent. I'd say either have rotate with L/R and shoot with SPACE, or rotate with mouse like you have and shoot with Left Click.
+ Some kind of UI is nice to show progression; i.e. health remaining, enemies killed, wave number etc.
