This was really fun to play! Managed to beat the hardest difficulty after several tries, definitely going to keep it in my library.

Thanks so much! Glad it wasn't too hard, and congrats on beating it!


Had tons of fun while playing each difficulty! It's very satisfying when things start going in the right direction and eventually overtaking the opposite team. 

The game had enough strategy to it, but wasn't overwhelming at all. 

Great job!

Thanks a bunch! Great to hear that it was balanced and fun!


I love this game dude! So glad you finally released it :D


Great to hear, thank you so much!


Love it! :D


Thanks! <3
