Congratulations on your first submitted game jam entry!
Played a couple of runs and liked it. I love the simple art style ... fits the genre well for me.
You asked for feedback on your project page. Here are the next things I personally would work on to make the game much more fun:
- Make the player not stop abruptly, but smoothly over a certain period of time. This should make it feel better.
- What about making the default falling speed higher? Or even better, have it accelerate by gravity! This makes it more dynamic and interesting.
- Add some strategically placed collectable items. This forces the player into forward thinking and decision making, and increases the replayability.
- Add some fitting background music. This adds so much to an enjoyable experience.
- ... and yeah, i would make the collision detection perfect. This is the most important game mechanic after all ;-)
And most of all, just keep making games and have fun with it!
