A really good start for an alpha build I'd say, I had fun playing this!
The physics seem to be a strong point, the bounciness of the slam attack and exploding barrels mechanic is quite satisfying, the placement of spikes and cover to create kill-zones was cleverly done too.
I do agree with other folks who've commented here that player feedback and reloading could use some improvement. A simple health bar and ammo-left indicator would make a world of difference. The weapon swap mechanic would feel a lot more intuitive using the left mouse button / right mouse button to switch between weapon types, or even just to trigger each type. Moving my hand to press 1/2 while trying to move to avoid enemies with WSAD was frustrating. I think with a little refinement you'll have a solid core loop for a fun top-down shooter with lots of potential!

Thanks a ton for the feedback! I also agree that some basic feedback about ammo and health, even at an alpha build, is a must. I'm going to make that an early next priority. And I also agree that using both left and right mouse buttons would be better. Really glad to hear about the feel of the core mechanics, thanks again!
