The art as a whole is nice, I like the thumbnail and the mech/bug designs, they look neat. Gameplay wise, it could use some work. That level up screen appears way too much at the start so for a bit there I was just not sure what was even going on, and it was very loud for me at least, had to lower my audio.
And besides that, its just hard to really understand what's going on. I'm not sure what the controls are, I don't know if we even have health, are there four characters? Its pretty hard to understand and maybe a bit of text at the start could help out.
But honestly, there is potential and I'm curious to see what can be done with this game!
