If you shoot a plasma ball, catch up to it via grappling hook and touch it it starts spinning around. Neat.

Nice. I got the secret medal :D

laggy. also when i try to grapple with the right click it opens a new page in my browser or just straight up goes back to the previous page. also the grappling is kinda weird. this is not how a grappling hook should work also pretty cool so far keep going this could be an awesome game in the future.

keybol responds:

Thank you for your feedback. I'm working on those issues you mentioned. I'm not sure about how it opens a new page though, are you playing in fullscreen?

Game crashes every time i press escape key

keybol responds:

I didn't put any escape command in the game, it's the fullscreen capability of WebGL. can you try on another browser?

Hey, the game is pretty good i would say, the hooking mechanic works well and shooting is good aswell, though there's no mouse reverse which is very annoying at least for me because well, i can't aim properly, also it may be purely my problem BUT sometimes when hooking the page with the game may randomly close, i hope that'll be fixed if possible, otherwise it's a really good game!

keybol responds:

Thanks a lot for your feedback. I'll see what is happening. I can also add a simple reverse aim option, that should be easy to add.
