This was stressfull :D
Nice idea, dude i'm bad at calculating

Cool game - really demands some quick thinking and reflexes. Very cool music also, really sets the mood for the urgency of the game. Only thing is that it gets too hard too quickly. Overall a fun little game!

Fun concept, but it ramps up crazy fast. On top of that, the game glitched and the cannon stopped working when I was playing.

May consider having the cannon auto fire when you enter in a correct answer, would fix a bit of the problem with the ramp up.

Hard time to understand the gamplay (numpad isn't supported) but nice concept. Really, 29*25 ?? Well done

This is pure evil. You can't just ask people to do math in games.
(Nice idea for unconventional weapon. I honestly did not see that comming :D )

Controls are broken for me :(. A nice idea though, and perfectly on theme. Cheers!

Interesting concept, but I think the execution could use a little work. Things get difficult way too fast. I think it would be better if your answers auto-fired. Also, and this may be my error, I couldn't figure out how to input negative number, or numbers with decimals.

the numpad thing got me too at first.

Nice concept but impossible to play, number buttons wasn't where they was supposed to be.

The firing was really unresponsive for me and as mentioned already the calculator glitched and wouldn't let me type in answers. Nice spin on the theme though.

I like the concept and mechanics even though it is a little unbalanced. Also it has glitches. But still, that is a good work! And I loved the music.

The difficulty ramps up really quickly on this one. Entering a number and then right-clicking and left-clicking (on a trackpad!!) was kind of awkward. Plus the game didn't capture the minus key so it popped open my browser's search box and took focus away (I use typeahead find).

Sometimes two expressions would end up on top of each other, which made them really hard to read. Using non-integer fractions (even though you use an integer answer) was a mindbender.

The idea is pretty good and kudos for working on something that could be good for reinforcing arithmetic skills. It just needs a little better pacing, streamlined control, and a little polish.
