Yoo I liked this a lot!
The shooting felt great tbh, I found it satisfying enough to keep playing for 20 mins or so
I think some kind of enemy that needs to be linked three times might be a good addition, but overall I liked the overall variety of enemies for the short time you had.
The 6th wave is hard btw, still have to complete it lol
Anyway, great job! If you have time maybe check out our game too :D
