Very well made game! Here is my honest review:
Pros
- Fun and simple gameplay
- Nice background music
- Funny propeller cat
- High score counter
Cons
- Hitboxes are really big
- Sometimes when blocks spawn they create very small gap to go through
My suggestions/improvements
- Make obstacles a bit smaller and bigger gaps between them
- In my opinion there is no point of moving horizontally (A or D) after scoring 400+ points, because blocks fly pretty fast
In overall I really liked your game. I hope you will continue to manage it further and release a full game. If you didn't understand something from what I have said, feel free to ask me.
