Kamio Recoil is an interesting game. Effectively a shmup that looks (and sometimes plays) like a platformer, the key to everything is in the "recoil" part of the title - not only do you shoot to blast away enemies and obstacles, but it's also your only means of propulsion. This takes ammo usage to a whole new level - run out of ammo completely and you will be stranded, completely unable to move! (Fortunately you can usually find extra ammo spread fairly generously around the levels). This brings extra strategy to the proceedings, as does the ability to instantly swap between your 5 heroines at any time - each has different primary and secondary weapons, which each have unique advantages and disadvantages.
When you complete a level you are taken to a screen to select the next level - there often divergent paths you can follow here - and finally you reach a boss at the end of the stage. I have to admit that I found this game pretty tough and even the first boss was a major challenge for me - though I don't feel that I'm particularly good at this sort of game, I trust you to know if you are!
The aesthetics were very retro, and this worked nicely for the game. The controls were responsive, I never found myself cursing the controls, only my own lack of skill at using them!
Kamio Recoil is a game that will appeal pretty specifically to those who like the games retro, challenging and a little bit different. It's pretty unique - at least I've never seen anything quite like it. If this sounds like your cup of tea head over to the game's Steam Page.
