Thank you so much for playing, @Dogveloper! We appreciate all feedback and you are 100% correct about the spawn rate. We will definitely consider this as we move to making this a full game.
We will be updating our progress soon on our website and instagram account so please check back periodically on our website (you can get our first game there, too!) and follow us on instagram for the latest updates.
I haven't had a chance to play your submission yet, but I will later tonight. Thanks again for your time!
