I am glad you enjoyed it! The balancing is a bit wonky, yeah, most of it was done last-minute at 5am haha. It is quite challenging in the beginning, I agree, I think it’s mainly due to the scarcity of cash which later on becomes much less scarce so you can afford more towers. If I remember correctly, the difficulty ramps back up around wave 40-50, so it’s worth trying if you have the time and the urge, I think that’s where most of my attempts ended up failing.
The music bug is a very silly one, basically, I accidentally forgot to put in a ! in an if statement that plays sound effects, so lasers and gas towers, which deal damage multiple times per second, cause the damage sound effect to play every single time it damages an enemy. This then overloads Unity’s sound system and basically makes it give up while the sound effects are playing, drowning out the music. You can fix this by turning the SFX volume down to 0 and the music should keep playing.
Thank you for playing! :)
