This was a pretty solid platformer. I enjoyed the platform/weapon mechanic, I actually jumped around for a bit in one of the bigger rooms mastering how to go higher and further without touching the ground. The lighting of the sprites was also cool, they seemed really alive and neon so nice work there. The name of the game itself also gets top marks from me.
I think the sound effects were a bit loud compared to the music and the scorpions' fireballs got a bit repetitive. A had some very minor graphical glitches with sprites not perfectly lining up, but this may be related to the web build. I think the level design was OK but could have benefited from more sections where the only way to progress was to use your platform/weapon.
Overall a good entry, well done!
