Antisquad

I did enjoy this game somewhat, but it only entertained me for a short period (a couple of hours) before I started playing something else, and felt inclined wanted to play this game again.

For $5 - take it, or leave it. I got impatient trying to get my character's up to a level where the game could have gotten engaging.

This is a mobile game thankfully divorced from microtransactions. There's a LOT of customability which requires multiple playthroughs of the same levels for cash but it's all in game, not requiring any real money.
It's a bit like X-Com except without the Random Number Generation which is good in that you can actually not miss constantly and bad in that enemies are equally capable of killing you VERY quickly. Surprisingly deep combat means you need to plan practically every move in advance and budget your action points. It's also a little frustrating because the all-important interface telling you how far enemies can move or see can be misleading and lead to you taking cheap shots.
No dialogue but there's plenty of personality in the very IncrediblesEsque art style and that style carries over to the music, cartoony effects, and environments.
It's a simple game with a lot of heart and a steep difficulty curve. If you like real time strategy and customization you could do much worse.
