Solid visuals on this. especially liked the way the control scheme was introduced (handdrawn?)
The balancing on this was good too, the fresh start felt limiting but fair, so as to allow room for death-and-upgrade gameplay loop with meaningful powerups. The stun feature was a good alternative over a player healthbar, making for a cleaner UI (just stand HP).
Some music would be good to set the mood!
Overall, solid, bug-free entry.
