This was really fun!
My first impression was that the music was pretty good and catchy haha
I liked it, at first I thought I could cheese it and just dodge the lasers but quickly realized that the energy doesn't refill the whole battery, so I actually had to try to collect them haha
A couple notes could maybe be that the jump height could depend on how long I'm pressing the jump button. It happened a couple times that I was trying to dodge two lasers coming from the same direction at different heights jumping between them, but I jumped and hit the top laser
Also, something that happened was at the beginning of the level a laser immediately hit me, there could probably be some sort of indicator when the lasers are about to shoot
Despite this, I had fun! I actually tried to finish all waves but it was quite difficult haha, maybe I'll try again later!
