It would be nice if there was something, maybe a bit of text that showed up, when your time ran out but before it got back to the menu, as it was sometimes odd for the shapes to seem to disappear for no reason.
The 1 million to win did not have the currency symbol, so it was not clear if this was using the same currency.
In the UI, the XP text once you reach 4 digits runs off of it's box and into the money box. Also, when the XP number is 10 digits (or 11 if you count the slash) digits long the numbers pushes off so that it is below the rest of the UI.
The lasers feel a bit too powerful to start off. I think it would be better to have them be something that has multiple levels, where it starts less powerful and end more powerful.
I feel like the upgrades push up too close to the edge as, especially when they are on the arrows, it can be hard to see all of the text.
It feels like sometimes I can get a bunch of double score boosts when I take out an enemy which seems to stack meaning that I get a really high amount of score from a basic red square.
Overall this was fun to play. I played until I got enough to win.
