I like the main menu. The gunshot effects were pretty cool too

Font in How To Play looks a bit stretched vertically.  Also, when I tried to shoot at them, I felt like their hitboxes were a little too small. They also drain your health pretty slowly.

very nice visuals and laser effects.  it could have more challenges and also rest in the middle.  I grew tired and for a moment I thought they weren't hurting me, they just loved me, but turned into pumpkin ):

Very well done, I love the graphics! 

I respect the emphasis on the visuals, but honestly I would expect to see some bigger variety in challenge, although the minor issues (like the cursor, and getting stuck on terrain) kinda made up for it ;P

Some features for the post jam version that would've been(??) possible to implement in the jam: 

• Seed-spitting green pumpkins (maybe?), some kind of poisonous terrain, finite ammunition; would have to go to the "stock place" to fill up

Cool game for this jam! I like the visuals and gameplay, but there could be even more juicy particle effects tho. 

Now, about some flaws. 
Sometimes bullets fly too far from the cursor. Also you should restrict space where player can walk, so it would be more challenging and fair. Music should be more cheery and exciting to keep player engaged. Also font in "how to play" is kinda unreadable, but maybe it's just me. Make the game more balanced and fair in general and it will be perfect!
