Fun Game, Slightly Lacking
I enjoyed this game, however, i lost interest after a little while. The levels are pretty repetitive and the gameplay could be a little more complex. Oh, the upgrade system was nice but more would be better. Maybe a few unique upgrades to spice it up.
Oh, the bombs should have a cooldown or something... not just expendable.
Hopefully that's a little helpful criticism for GlueFO 3.0 or 2.5 or whatever. Thanks for the fun.
