Hole Punch: Sling your spaceship around gravitational fields

Great game, though the controls on mobile are a bit too imprecise.

As you drag a hole, the size widgets should disappear so you can better see what's around it. They could pop back up again once you're done dragging.

Personally I'd rather if you had to press a button or something (or long press?) to add a new hole. I keep accidentally adding new ones when all I want to do is adjust an existing one.

Also spamming the user with the help screen right off the bat is a bit much. As long as they know it's there and can pull it up / dismiss it, I think it would be more fun to sort of discover the game mechanics yourself.

Note several of the first 8 or so levels can be accomplished with a single minimum (8) sized black hole. Eg. I liked the simplicity of doing that on level 6.

I just spent a ton of time on this. Reminds me of the joy from those old flash sites like addictinggames.com. Bravo.

Fun idea, but kind of maddening that I can click and hold to add mass to a hole but if i overshoot, i can't do anything subtract mass or delete a hole.

Click on the hole. There will appear 3 buttons, one to add mass, one to subtract and one to delete the hole completely.

also need a way to increase the sim speed. 1.5x 2x etc

Definitely a fun game kudos!

The ability to subtract mass is definitely needed. All you can do is click “undo” and try again. You can drag the holes around too. Still pretty fun, I played 5 or 6 levels

I just pushed an update. Click on the hole and controls will appear. I think you'll enjoy the later levels (10+)

Tap the black hole and it gives you ability to add and remove.

This is the year of old browser (and/or flash) games making a comeback in some form.

This is kind of a cool concept. It's like Space Golfing.

Another alternative is to make it like a turn-based Scorched Earth (Mother of all games), where you can either

1. launch asteroid size projectiles across star systems in a field of stars and black holes to it each other.

2. launch projectiles that then place black holes (perhaps either by timeout or signal--taking into account the speed of light!) to change the field.

It's a good start!

Scorched Earth <3

Another version of this idea has been out for some time now, check out Interplanetary[0] (85% off today it seems!)

I know right? As soon as I saw the page, I had a rough idea of how to control things already. lol

Thanks! I like the keyboard experience (space for start/stop), arrows to add/subtract mass. Maybe I will add tabbing

Very nice, being busy with sth, and I could not go through all levels and reached the one with star(sun?), but the topic of gravity assist manouver was always inspiring for me, so I enjoy this game, congrats on making it!

reminds me of Gravitee, except in that game the planets are pre-positioned and you're hitting a golf ball

It’s nice but clearly designed for desktop

It’s a mobile world. This would be so nice as a proper touch enabled game

Clicking too fast zooms the browser which breaks the click placement. Native Mobile would be much better.

Great concept!

Desktop and Mobile are at about a 50/50 split, no it's not exactly a "mobile world".

It might be a cheat, but I'd really like a mode where the projected path of the ship had unlimited length. The trial and error cycle is a bit too long for some of the more advanced setups.

Loved it! Played all 20 levels

Some missions have mass budget so large it seems to imply a "go fast, crash fast" solutions, but there's no time-of-flight score :(

ha, now I want to see a leaderboard, with players' score distribution (mass/holes/time mb?), like the zachtronics games

I had a blast. Thank you!

Feedback:

- It would be nice to be able to manually key in the matter; on Safari desktop clicking uses up matter too quickly to set precisely.

- Key to speed up time once running.
