Pretty cute game, it has some solid pixel art, the level design and enemy placement are really clever, and all the movements feel good. I really expect a lot of things of this game!
I know it is in a really early phase of development so I can't really complain about not having certains things, but the inexistence of checkpoints, a restart button or at least a health bar make it really hard, I didn't even get to see the end of the level yet! because of how long it is and the quantity of enemies there is is really easy to die and you need to start over again.
And the last thing, when your are trying to get to a platform using some kind of ladders there is a snake in the above floor and it just fall over you (killing you instantly). That's cheap man (?)
Anyway keep working on it!
