Haha! Yeah didn't see yours on the list (though there are nearly 400 games lol). Just played yours, indeed almost the same idea! Great minds think alike! I didn't create the model, (it's credited in the credits) though I did go for a 2D game at first with my own art that looked even more like yours! I just went for a clicker in the end, but really like your idea of swatting the bugs with different limbs. Combining mechanics ideas could be fun :)
Two ideas I've thought of since the jam are:
1) A boss fight.. so that once you've swatted (or clicked) a certain amount of bugs away then there's a pause, maybe a bit of a screen-shake as an enormous human-sized bug comes into the room and you then have to fight it off while it's chasing you round the room.. (maybe you inexplicably get some kind of gun at this point, or pick one up that was hanging on the wall).. that would add a win condition (at least to my game which is basically just they always drive you mad, just a question of how long))
2) (This may only apply to 3D, though could be possible to reinterpret for 2D).. An option to either play as the human, or the bug (which would then be first person/first bug view), then you get spawned and have to bite the human before you get clicked/swatted. This could be really short (basically just an extra mini-game that it's possible to play for a laugh, you win if you bite the human)..
2nd idea is more daft, but could be amusing if it was an option (or indeed it unlocks as an option if you defeat the boss bug).
What are your thoughts on other mechanics?
Thanks for playing! :)
