Thank you for playing and the feedback! <3
When i made this game i didn't have headphones with me, so im sorry for the bad volumes.
For the difficulty, some said it was too hard while testing, so the gamespeed at the start is capped and goes up to 100% in like 6 waves, but it can be turned off to have a more difficult time right from the start. I could've been more transparent with that info. I wanted everyone to have a great time, so with upgrades you are also intentionally overpowered. Without upgrades and having lost 0 lifes in your first try is seriously impressive imo, you must be at the top skillwise. When i tested the game it was possible for me to do what you did, but i thought its just because i had practice with it.
Its really hard to make a game that is fitting for every skill level, if i had more time i would've made a hard mode tho. But now the goal was that the game can be completed at most around 10 minutes with the player having fun, and ultimately winning.
I'm sorry for the music, if updates would come, it would be the first to change as many pointed out it was bad, lol.
