Thank you for playing and the feedback! I agree the upgrade menu was a little forced because it was literally the last functionality I added in, and I wasn't sure how to add it to the next level screen. I thought to myself to add a restart button to the game over screen and win screen but was one of the details I had to skip on for time. The golden swat charging is definitly something i want to add as well. Thank you so much for noticing the blood splat! A lot of time went into that detail. Thanks again for playing! :)
