happy to hear you enjoyed. Level 24 on hard is really good going :o
Buffs applying to both goblins was quite a late change since it was making one goblin type feel quite useless. Frost goblins are actually a little different from the other types as it heals rather than gains damage like the other 2 elements.
You're not the first to say about the sounds getting a bit grating so I'll try improve on that, I was trying to get the bloons td or risk of rain type feel where its a hit sound that can be repetitive without driving you crazy but I can see how it can be a bit much on the current version.
Since the jam ended I've continued some development on the game with some pretty major reworks to the gameplay to make it more interesting and how stats work to help make it easier to keep things more balanced in future. Goblin knights, lil guys and a reworked version of devils were all pretty late additions before the deadline that I accidently power crept above any of the other upgrades :')
The plan next if I continue on this project is going to be adding a lot more variety to the gameplay beyond just the attacking the tower/roulette wheel and adding a lot more decisions to make when it comes to scaling in different ways. Theres already a few more stats added in the new build such as crit chance, crit damage and health regen.
Hoping to have an update ready to share once the jam is over. Thanks again for playing and feel free to follow me on itch if you want to see where the games goes
