Lots of problems with this "game", some of which are as follows:
-Unclear victory conditions
-Unnecessary Controls menu
-Super small timer (which doesn't do anything when it hits zero and starts counting up again)
-Unclear interface (e.g., wtf is the red bar? Is it a hp bar? Because I can't tell)
-UFOs that ALL have the same speed & AI behavior which led them to being easily clumped & dodged
That doesn't even cover that the visual resources leave me wanting.
