quite good for a first try!!
the game is quite good for a first try! i've seen far more worse!
as ganado already said, respawning at the same place is not too clever.
also, i'd like to get a better response from killing enemys. (maybe a small bump, then i would be also possible to pass an abyss by killing multiple flying enemys)
music is okay, the sound isnt very nice (the jumping "sproing" is extremly annoying imho, because u jump a lot in this game)
graphics and animations are also not very beautifull (they are also not excessively bad, i really like the way the dinosaure are drawn, especially their facial expression)
anyways: zombie dinosaurs. wtf!? this is the most awsome idea ive seen for quite a while
im looking forward to your future work! (or maybe an revised version)
keep up the good work!
7/10 including one "first try bonus point"
