I really want to like this game; however, the balancing leaves a lot to be desired. Some of the powerups in the game feel like they have little to no impact in battle. for example:
-Homing is completely useless by all metrics. In early levels it's completely negligible and it's extremely hard to notice if it even does anything
-Fire Rate feels extremely underpowered, early it makes no difference, and it feels more like a long-term investment then an actual good powerup itself
-Freeze is only really good if you have Pierce, if not then it's useless
Another problem (though this is just my opinion) is that the powerups are kind of generic as well. They do their job I guess but it'd be nice to see a lot more variety in powerups than the choices we have now.
It also feels like the biggest enemy is really the Shop. Early-game a majority of your time is spent in the Shop to get anything more impactful as you're in a race against time before the first boss drops. It sounds pretty engaging in text, however in execution you're it's a lot of rerolling useless powerups which takes up a lot of your money fast. (Rerolling also costs more each time) In addition, the Shop can show multiple of the same item so if it's too expensive early (multi-shot lvl 2) or not the best then you need to waste more points in rerolling. All of this in the small span before the boss spawns.
Don't get me wrong I think this game is extremely creative, it does have a lot of aspects that would be fun if not for the balance. It's not really the enemies that are the problem, it's more just these underpowered powerups that negatively impacts the fun of the game.
