It will do pretty well relative to most games. It reminds me of a very popular game, TIS 100 by Zachtronics. I loved playing it, and this is even better!

Of course, nobody can guarantee success. Failure is healthy. This is definitely a great product. After I played that pesky block welding game and enjoyed it, I looked at your other work recently and found it all top notch. This one seems to be the most commercially viable, in my opinion. I would also pay if that slime puzzle became a full fledged product.

Your work ethic and planning skills astound me, brother.

It is so good that I think someone might steal it if you do not turn it into something more. I would have added a graphical Scratch like option for kids, though. I will definitely let my son play this game. You really did great! I mean professionally great, not hobby great, which is also amazing.

If you put it up and let it accumulate wishlists for some time (and maybe try to promote it on YouTube or something), you could probably get good results if the price were reasonable. If you just release it silently, it probably won't do well. 

If you're not confident, you should look at similar games first before you spend the $100 to upload 1 game. Look at how paint warfare turned out. This is a great game but it's best to not go all in you know?
