In short: messy. Bad onboarding, tons of things throwing at you at the very first seconds of a play session, an intro text that makes no sense in terms of both the gameplay and the theme.
But if refined, this game may be a good thing to sell (and buy).
Switching between characters turns into skill, but I feel that it would be better if their abilities were recombined into one character with both grappling hook and jetpack as this "skill" is eaily achievable in one minute. The rectangle just makes no sense as it is slow, is a big target, and weak at the beginning.
Another bad thing about characters is that if one of them dies you a) lose its abilities; b) lose its weapon, if any and c) lose ability to move in many ways, which does make the game fun and, well, you can't do much with the circle only.
SFX and music are great.
