Cool looking game but damn is it hard. The game is very stingy with checkpoints so it's hard to proceed. Movement is a bit floaty and I don't really like how the weapon always points downwards when attacking in the air. The first item is not taught very well, the game tells nothing about it. The teaching element with the rope is done in a much better way as you can't proceed without learning to use it. I also don't know if the letters do anything important but if not, they're too much hassle to be worth collecting.
On a positive note, I liked the graphics, the sound and the level design. I especially enjoyed the sections where you had to use the first item to dodge spikes and mines or climb upwards.
