It was a fun arcade game. I liked your artstyle, you captured a look that is very reminescent of a child's imagination.´
I found that you often got stuck in platforms when you jump next to them - I died twice because of that.
I think a bit more enemy variety would help this game a lot! I enjoy your artstyle a lot so I'd love to see what enemies you would imagine next. You can play with their movement patterns, like having an enemy that moves in a loop, or another that just moves back and forth across the top of the screen shooting at you for example. Or even just a slow-moving, non-shooting, tough enemy that takes a bit more to defeat.
Overall, good job! Well done, I enjoyed this entry :)
