There are a few medals that aren't functioning correctly at the moment. They will be fixed in the next update that also includes a revamped Endless Mode! Thanks for the feedback!
This game is so frustrating. After first few levels that are easy as pie, the nest few require lots of patience and stress. The control scheme is just gruesome - WE1234. It's just ridiculous and VERY uncomfortable. Its full of bugs - in one mission all enemies were stuck in the ground and one of the objectives was to kill them all, also while playing I accidentally pushed some button and all music and sound went off... except at the logo at the start of the game. After some random button mashing I discovered that - and = controls the volume and somehow i managed to put volume all down with just one time pushing it. Also it is not listed in the controls. All in all, no game has irritated me so much in a long time 2/5. After some bug fixes and control customization it would be much better.
Thanks :)
