Thank you for your comprehensive feedback, it is appreciated :) As soon as I read "skeletons" my first thought was "TREX" xD but maybe that's a bit too big for Tom to push around :p and it wouldn't fit the mu(mmy)seum...
I think other types would need another interesting way to handle them, but maybe we come up with something. After the jam we will probably finish the third level and build the planned outro-sequence. Actually we planned that mummies would be alerted if Tom runs into an obstacle too often, but time time time... That would give more opportunities for interesting level design. Lets see if I can overcome my laziness xD
