Nice little game! I'd say that the main gameplay issue is that you can spam click to have a machinguning mortar (which is fun to see tho :D ), making the game probably too easy. You did an excellent job though, it was fun to give your game a try!
Thank you! Yeah, maybe something like a reload timer could help with that. Might add something along those lines, so thank you for your feedback. :')
I now added a small cooldown. It isn't too noticable, but really helps. Feels much more rewarding now. Thank you again!
