Nice little game, decent survivors-like gameplay here. I do find it odd the cactus has collision when nothing else in the background does, and I do feel that 20 minutes is maybe a bit too long for this game, but otherwise it was a fairly solid entry.

I enjoyed the core loop, I think the effect of every shot was very satisfying and i like the artistic choice.

 However i think you did not play the game yourself very much, after like four minutes it becomes very repetitive with not much change except the price increase of the chests, which contain little to no useful content.

The wheel itself also feels like its just there with not much purpose. The first few spins select the guns, but they dont even tell you which ones you could get. And they're not balanced in my opinion. I got three blunderbusses on my first game and then a bunch of heals when i was on full hp. And then at the end of my last game for many of my wheels (when i was on 1 hp) the heals  did  not even  appear on the wheel.

Also the game just stops at the "winning" 20 minutes, the enemies and the timer freezes, not much happens, no victory screen, sad :(

But that being said, the parts that worked for me were in my opinion really good!! 

I think the art is really cool, and I like the idea of spinning to upgrade my stuff. I think that there should of been a better visual or audio indicator for when the player takes damage. But other than that, the game is pretty solid overall.

This game was very well produced and balanced. I could feel the difficulty ramping up while still enjoying the power that came with each upgrade. Even with explosions and metal music ramping up, the audio and visuals were still clear and readable. Everything was responsive and worked well.

In implementing the theme, the game took away one of my favorite parts of the 'Survivors' formula: Choice. Without any options, I was unable to strategize my build in the slightest. I at one point received 7 bullet size upgrades in a row. Another time I was healed when already at full health. I'm not sure where else you could go with the theme here, but taking away player expression is not my idea of good theme usage.

Game also went unresponsive when I selected to quit -- I'm assuming because that button was meant for a different platform haha.

Good game overall, I just spent a lot of time above explaining my one complaint.
