Nice Game, I have a suggestion though, perhaps you could add a coin door, so people would also need to collect coins, you could also use these coins to keep score and be able to change the coin door's properties so that for one door you need 10 and the next 15, this would add a little challenge and also make the game more enjoyable. Another suggestion is to add keys, one key is used to open a door and is one use only they both work in the same way, it's just a matter of what's easiest to code for you. (+ if you want this, - if you don't)
Great game ^-^,I completed it fairly quickly,and got all of the badges in one go,Maybe add some more bosses?T-Rex was a nice touch.And maybe another badge that will challenge the players,Such as...Beating the T-Rex in (This amount of Time)
Very Good Game!If you don't mind,I have some suggestions for the next version,Perhaps some Melee Weapon(s),More Gamemodes(CTF,Team Deathmatch,More Moving Koths for Arenas),And maybe if you could make some more Arenas for more variety,thx
