Cally's Cave 4 is a run and gun action adventure platformer. It's got many interesting mechanics like evolving weapons, weapon parrying to reflect enemy bullets, and a radar system that rewards players for clearing a map. Personally I feel the developers overdid it and the combination of all these systems takes away any challenge of playing the game.

The game is great for those looking to get a bit of a power trip as Cally is super overpowered compared to anything you'll ever face, but it gets stale once you realize that, even the final boss will fall in seconds against certain maxed out guns. Even if you do manage to keep your weapons underleveled, because enemy damage never scales, you would need to take 15 ~ 30 hits to exhaust your health by the end of the game, not even considering that you have 8 backpack slots to hold Chicken Fingers which full heal on death.

I found the story very generic and constantly references the previous games which I didn't play. Overall I think this game is more directed to children with it's incredibly forgiving nature, but it's got a lot of interesting mechanics which are worth checking out.
