You deciding if you want to keep working on it is your choice. 

Im only here to feedback on the experience

• First is presentation, a layout thats more centered plays and reads better.  showing the boarders of the arena is also very good since you want to know what and where the game begins and ends. Having a Physical shop In the arena is more fun but also  Reminds you about that choice of buying, An "I" for shop isen't really something you will notice that easily
• I think waves would help this game a lot. a timed pause until you get hunted by more pumpkin creatures
• i found it a little intersting how  you aim and miss most of the time. I think it wouldent hurt to have the collision of bullets hitting be more generous. also if the enemys shake or something for impact feedback.
• A soft moonlight (Directional light blue color low intensity) in the scene wouldent hurt either to sort of make the whole game more readable
• I dont super like the Glidey feel of the player but this could just be me. I like things to be very direct unless the game is about Having flowing movement that extra glide doesent help when you are maneuvering between enemys as you glide into them.
• dont let the player go outsied where the enemys spawn. have the enemys come trough predictable gates.
• I wonder if the reload mechanic is really needed in this game? i think it would be fine if you had another mechanic that supplements that like a dash move or something that you can do whiles reloading but, i think after 20 bullets most of them  miss the target it feels a little bad.
• music is fine the audio is fine.
• the fail state should be harsher. Give me like 3 health and the choice to upgrade my health.
• Picking up candy is the point but I feel like it sort of needs.. Something more but it's fine i guess =D
