Android game ideas?

My friend and colleague left my current project in another town accidentally and it's not that easy to start programming same game again, so that's also the reason why I want to create something new meanwhile.

I tend to gravitate towards puzzle games when I want to play something on my phone, I think the touch screen controls really fit the genre better than any other. Moving objects, pressing buttons, conecting things, launching stuff, etc. feels very natural when there's no abstract controls inbetween. On the other hand action games just seem to beg for a more traditional set up with physical buttons.

I've been recommended something like Vector. Should I go for it?

(endless space shooter)

How about a space shooter with handcrafted levels (not procedural generation) and an ending? ☺

how about an endless runner?

on mobile i like to play games that can be split into smaller chapters/sessions
try looking at retro games from 90s for inspiration

If you want them to be at all successful, don't try to develop two games simultaneously. You need to focus and immerse yourself in the development. I think it's naive to think otherwise. If however, you've run out of ideas or motivation for the first game, then sure put the first aside for a while and do something different.

Also regarding the $100 - I assume you are referring to Steam. There are alternatives like Itch, using your own website and promoting on social media and trying to get exposure on industry sites.

A chill platformer with rpg elements would be cool to have since that's a rarity nowadays
