The game is pretty nice, but it is also a tad frustrating in some place.
Controls -
This control scheme is just weird. Arrow Keys + X / Z to do things is fine, but then randomly having A as the jump button in place of either C (which would be right next to the others) or Space throws things off a bit, and is a bit awkward to play with.
Combat -
The lack of Invincibility Frames means groups of enemies can easily kill you due to the three health limit, and lack of health recovery makes every hit devastating. Pherl's short attack range as well doesn't help matters, nor how common it is for enemies to quickly spawn and form into a mob on top of each other with your attacks only affecting so many at a time.
In particular the cowgirl enemies in the desert level show how bad it can get given their fairly generous range with their molotovs.
Quick Suggestions -
Increased health to around five bars, and the addition of invincibility frames upon eating an enemy or getting hit by an enemy for a few seconds.
Rebindable Keys, or switching the Jump Key over to Space.
Have Attacks stun the enemies for longer periods whilst keeping their spawn rate, giving you more time and breathing room to take others down whilst those you attacked are still stunned.
