I loved seeing all the different enemy types, especially the ones with little telegraphing or attack animations.  I only wish all the attacks were animated like that! 
Some of the visual design, especially the text and backgrounds, could be a bit clearer. Some backgrounds were a bit visually overwhelming (stripes), and the dark background obscured the health bars of enemies. The placement of the secret region was a little hard to discern, I thought maybe you had to punch the sign or each of the dummies? But I did find it in the end. Impressive work for one person and a first jam!

This game is good. I think you should add Game Pad support and Level 3 Island is bit tough with these dogs attacking the player.

surprisingly fun and i liked the art, very gameboy-like

It was a nice submission. I liked the art and the music. The font was very hard to read though. Keep un the good work.

Hopping from island to island to see new enemies with different fighting styles. The bosses are fun in their own way, from the dogs to the big Brontosaurus.

Love the dinosaur guys, and the enemies telegraph their attacks really clearly

This is a fun submission! Simple but the combat was entertaining. Good job!

I love the design of the dinosaur guys.

The final location of the treasure was a surprise. I did read the signs but didn't pay much attention to them so I had to go back. 

Damn, wasn't expecting to dust off my dark souls muscle memory for a gbjam entry, but here we go!

very fun entry! I found it very effective, and always surprising! Realizing I hadn't read a sign for the riddle I had to come back, and was actually surprised I didn't have to redo all the 3rd island to get to the sign, given the difficulty of some fights! xD

Solid entry in my opinion, hope you had fun making it!

I really like the enemy variety and the attack telegraphing. Sometimes the enemy melee attacks caught me off guard but everything else they did was very well communicated. I did sadly fail to find the secret though. The controls on the map section are weird and inconsistent, and also I managed to freeze the game there when moving to level 3 somehow? Didn't happen on a replay

Nice work! The dogs are a little bit too hard to fight; I don't get how to defeat them without getting hit. The roll you do to avoid shots should speed you up for a moment—it would make it more immersive.
On the sea map, it's a little bit confusing that I have to press up to go left (level 2).
Also, it's strange that you have to press Enter there to confirm, but on the level itself, you just press the A button.
But I enjoyed it!
