Thank you! For the difficulty, the game was basically impossible to beat about 4 hours before submission, so I had to do a ton of trial and error to get something beatable yet difficult, but i'll definitely tweak that for next time ha. And about the orignal towers (cloud, balloon and thundercloud), originally they were gonna upgrade to the new and better towers, however it turned out (due to their price) softlocking yourself was very easy if you didn't plan ahead. But I'll definitely try and work something out for that, thanks!
