[Android] Free - Space Hobo (Was $6.99) - Google Play

Not sure how long this is free for. Looks like a decent android game with no IAP

From the Google Play site:

This is an arcade strategy game, where you play as a space hobo, whose cardboard box has been stolen.

All gameplay is about balance (like rock-paper-scissors) and unlocking pets or special abilities. Put the right "ingredients" on the battlefield and watch how it plays out. And if your robots are losing - change your strategy! Shoot enemies with special abilities! Throw your pet into battle! Replay levels with other pets or abilities!

This game mechanic is very popular in fantasy settings, but here instead of castles, you will be storming a gang of weird space creatures.

Available game modes:
- Story mode
- Local PvP on the same device (hot seat)
- Survival mode

Additional features:
- The game has a storyline and a logical conclusion
- Unit defense. It's like tower defense, but with units
- After completing the game, you can keep playing in the endless survival mode
- You can also play it with a friend on the same device
- And in case you don't have any friends, you can play against a bot and imagine that you have friends
