Hello!
I enjoyed the game overall but did feel like for the simplicity of it the level unlock requirements were far too long. After unlocking level 2 I got to 2500 before giving up because I just felt like there was no real challenge and didn't want to spend the time to unlock level 3 and then keep playing past that point. I would shorten them substantially. I did instantly feel the Jetpack Joyride inspiration even before I read it on your page, it felt similar in control scheme. I really liked the concept of the player bubble expanding in size as you gain the health resource. Felt kind of similar to the phone game Osmos if you have played that. Maybe consider zooming the camera out a bit and leaning into that aspect of the design more with a larger limit on player diameter and more obstacles? I also think adding a 'pop zone' or something to the spiky rocks on the roof might be an interesting addition. I assumed I might pop if I hit the spiky rocks but when I tested it I just went through. I think if you continued to expand on the concept with more variety in the playspace it could be a very good phone game.
UI and controls were simple and readable, got the point across. I liked the simplicity of the controls and given the possibility of porting this to phones it makes a lot of sense.
The music and sound effects were good. I liked the background music and the menu music was a bit of a jam :)
Good job overall though, definitely a solid foundation to build upon!
Our team have submitted a runner inspired game too that combines Tetris and precision platforming if you'd like to check it out (Link below). :)
I wish you the best with your projects!
