Hook Line

Very interesting game! I included it in my GM48: One Tool, Many Uses compilation video series, if you’d like to take a look. :) https://youtu.be/VY1l7qmII10

As other have said, the spawning code needs a lot more work. Out of a dozen tries I got :

• instantly killed 3 times
• spawned in a wall once (I guess it's because the player object has its origin in the center unlike the walls)
• spawned... nowhere 3 times (which threw the game in an infinite loop and I had to kill it in the manager)

Also, like Kwis said, it's kinda infuriating to make us lose time to restart by pressing enter. You want to let the player go back almost instantly, especially in a game when you can die so fast. There are other way to prevent an accidental skip besides having the player use a key that's never used elsewhere in the game.
Oh and if you let the player use the arrow keys, make sure you can jump with up instead of space, because people don't have 3 hands and that's something I've seen way too much in this jam.

On the gameplay side, I'd say the game is too fast. You either get in a safe space and collect things from there or get killed almost instantly by turtles.

Love that you did procedural generation. There were a few things that broke it for me though:

The first time I spawned I had no clue where I was (the arrow pointing could have been much bigger). The second time a bug spawned right above my head and fell on me and I died right away. The third time, the portal spawned one block to my right.

A few more checks / parameters to keep the player from spawning near a portal / bug and it would have been much better.

Good job with the loading screen, but just one design note, I had a hard time keeping track of the player character during game-play because he was so small. If he had been the same size as the blocks (err... volumetrically) it would have been better. The same goes for the bugs. Felt like they should be the same size as the coins. Or you could have just zoomed in the view a bit and had it follow the player, because I did like the larger room design.

Also, the tool didn't seem to have more than one use :)

Wow hem... okay.

First of all, the game is at first VERY confusing. It took me to come back into the page description to check if I forgot a very important information. Turns out the player may start aside an enemy and it happened often. But I guess previous feedback would have already told that.

You need to have something more than a black arrow to make the player notice the player cause i had to restart a bunch of times before getting where you were supposed to spot the player. That's already a bad sign if you have to get where you are.

The fact that the level is auto generated is nice but sitting through it is a bit annoying to me, you're just left waiting. It shouldn't take more than a second in my opinion.

Also, avoid using "enter" to restart; it's not convenient when the keys are A, D, space and mouse (cause your hands are on the left and right while the enter key is between those, forcing you to move change hand position; it might seem like a small thing but it still feels tedious)

Really loved the room generation, though unfortunately I did die on two occasions after it had finished and I pressed space to start like Joseph mentioned.

I played on HTML5 and the room speed felt great not too slow at all :)

The control on the grappling hook was at times difficult, but otherwise I really enjoyed playing the game, with a bit of smoothing out I could see myself getting hook!

Presentation is pretty good and the gif icon made me want to try it. I like the idea and the randomly generated algorithm is pretty cool. I really like that I can watch the level as it builds, that's always been something interesting to me in games. The music is kinda catchy too.

At first I didn't realize that I could just click the diamonds and the turtles to collect / kill them, you could add that to the controls description. It's also hard to control your momentum while you are grappled (I wanted to press up to go up but I just kept going down for example), and I often got stuck in the walls while trying to jump away from enemies. Also, it's hard to track where your character is at the start of a level.

I managed to get 340 points but after I beat the first level I died while the second level was generating (I'm guessing that a turtle spawned on me).

If movement with the hook was smoother and the bugs were ironed out, it could be a lot of fun. Good job. =)
