i like how this is kind of like metroid, but i was just running around randomly and felt i didnt explore some routes available, and still ended up at the boss. not sure if there actually were other routes or it just looked like that because it was so dark.
ok, 2 things: i accidently clicked "back to menu" and was reset to wave 1 when i loaded the game again.
and: its really hard to grad the energy ball, you have to be too precise to get it.
other than that a great game, i liked it. 4/5.
its a great game, but the character keeps running towards (or at least not away) from the enemy-mushrooms if you click away. its hard to trigger their explosions without getting hit yourself.
i think the top of the games screen if being cut off?! not sure though, but for example, on top of the "game over" there is text which i cant read because its mostly cut off from the top border.
