Hey, firstly, on the positive side, the music is pretty great, the background image is cool and i like the graphics style BUT you must make some animations for your player (aka great little elephant).
The main menu also looks great !
On the negative side, you should make the movement a bit sharper using GetAxisRaw instead of GetAxis, so it doesn't smooth the input. You should also make the level 1 a bit easier so the player doesn't want to quit in the first 5 minutes. And as i said earlier, the elephant is a bit small, maybe you should make it a bit bigger.
So, to resume, there are some great things and some bad things, but overall it's an okay game !
Finally, could you rate my game ? Thank you in advance !
