Overall, not a bad game. I think that the game could definitely use some improvement in the level department. Lots of levels had slow starts, were monotonous, or were just flat out boring unfortunately. I think some new mechanics being introduced throughout the game would make a big difference. The pacing was also a bit strange, with loooong stretch in the middle feeling very repetitive to the point of being boring at times. Around level 25 and beyond, things started to pick up again with the challenges and new obstacles introduced around that time started to make things fun again, but by then the game was just about over.
As for minor issues, there is a small bug I found where pressing space as the level begins flips the control scheme, and the music never seemed to loop right. There were also some minor hit detection problems with the arrows, but those weren't game ruining.
As far as positives, it's a simple, easy to understand game that I could see being a great time killer on a mobile device! Some more levels and more mechanics would go great with this game in my opinion. Art style is nice and simplistic, though some objects and backgrounds wouldn't suffer from a little spicing up. The music is nice, aside from the aforementioned looping issue, and the challenge that the later levels introduced were fun to play through. All in all, a solid game with room to make it better! 👍
