I feel like you've got a lot of potential here, the idea of leaving a trail to make your future runs more difficult is really interesting. I found that the interval between the bullets being created was a bit too short, and instead of it becoming a bullet hell they were just too close together to the point where the only way to get through was to simply damage boost. With some extra types of bullet shooters I think you could have a really interesting bullet hell game, great work!

The game just crashes when i try to play it :'(

There was some really cool presentation here you artist did a great job. it's also cool seeing the trails of my decisions and actions haunt me as I continued to experience the game, not much else to say really this was a pretty fun entry! 

I love the menu animation, it's so simple but has a great effect! 

I like the interpretation of the theme! Has a good vibe and difficulty management.

It's not bad. Making your path your problem in the future is a good idea.
But I found small problem. You can just damage boost to the island. If you just make the map bigger or (and) the invincibility frames shorter, this problem will go away or be less noticeable.

Very impressive for 4 days even for a team and very cool concept. The UI does feel a little out of place tho imo. Can you also rate my game?

I was able to make it to trip 12. Pretty clever to have projectiles spawn based on the path you took the previous round.  Seemed to me that the strategy is to go vertical as much as you can since that is how the projectiles are moving, becomes pretty hectic otherwise. Good job!
