The glass blocks are really erratic. Sometimes they crumple from a block resting there, and sometimes they withstand a giant box dropping the whole screen on them.
The shooty thing before the N. If you can't kill it, you need to indicate that. It's the same color as the bugs, and it looks the same as the bugs when shot. Make it a different color.
Really good, but jumping is way too high and floaty, and the camera snapping when the mouse passes over your guy is way too harsh. Can't shoot someone below you because it freaks out.
Weak! Game is awesome, but since the left corner is off map the underground guys can go down the left edge, come up off screen, and then anally probe your whole force.
Many RPG fails. Guns don't gain anything on melee. Stun grenades are useless if they don't last more than one turn. And most importantly, all enemies need to attack each round or there is no difference in any fight.
When HIDE pops up, your key key repeat is broken. So you stop until you press again and die. And why does it say Hide anyway, when you need to just shoot the thing with the same circle strafe that defeats every other bad guy?
