How else have you attempted to promote it?
It is a casual idle game - have you attempted to contact casual idle game players/promoters, twitter, youtube, game journo types etc. Do casual idle game promoters exist?
How about write an article about your development process, your situation and ability to develop games while on travel/commute? Every time you mention the game - it will be hyperlinked. If some read the article - some may even click the link, and of those that click the link 10% might even download the game to check it out.
Personally - all 3 games you’ve uploaded to google look like they could be created by anyone following a tutorial. They have no innovative elements, and they are very - “already seen that somewhere else, but better”. So - that’s probably why the game is not getting any downloads. Also - if all your friends (number?) have received the announcement and still have not downloaded the game - they are silently telling you the game is not interesting enough to even check out.
Some suggestions to proceed;
#1 - Move on to your next game. I think you are on a winning creation path - creating small, simple, single mechanic games that can be developed in a short creation cycle.
Although I dislike single mechanic games, my view on that kind of game doesn’t matter, there are some popular single mechanic games that do well.
1a. Consider a tiny bit more complexity in your next design, something beyond single mechanic, casual/passive play.
1b. Brain storm on an innovative idea, even if you are creating a single mechanic game. The games you’ve released already are “me too” games - there is nothing in them that I can not find in another game.
1c. Paper prototyping is a beneficial element of design. Consider performing paper prototyping until you land on a concept that is enjoyable and works. Then move along with design and into development.
1d. Strongly review presentation of other ‘like’ games once you set upon developing your next game. How are they presented, do they have high FX value? Several questions can be posed and addressed to increase download value - that you should think about.
#2 Improve the existing game. You might consider some elegant particle effects to add to the games visual appeal - I doubt it will result in anything beyond a modest improvement in downloads, but it you are interested in improving what you have - that is something that could improve the current experience. Check out UltraFlow for reference.
“The goal of the game is to destroy as many boxes as possible, and avoid them reaching the bottom of the screen. If you do, the game is over. You may restart the game, and play for as long as you like. How far can you get?”
This description is very dull, as is probably (honesty) the game based on the target demographic. You might consider spicing up the description, but you want to avoid false advertising, so - this is kind of the problem. The game isn’t fun so the description - accurately describing the game is also - turning away players.
• This game features a flat, sleek design that not only is eye pleasing, but keeps you coming back for more.
This is listed as a feature however in my opinion it reflects the low appeal of the game. Where some may see flat, sleek, clean, eye pleasing as welcoming - in this instance, for this game, it reads as dull and unattractive - because it’s just - low effort. Not saying you didn’t put in effort to make the game sleek, but sleek is kind of the default state, maybe ad some visual flair to the game - some elements that are appealing that add visual interest, some “character” to the game.
