OMG guys! I'm finally level 3! I unlocked more new items such as the message, megamines, electropede, bugmeister, and mogura! Hope you like this game, too! Comment on it and enjoy!
Here's some information about the enemies:
Mogura- it comes up from underground and attacks you and your allies.
Electropede- a improved version of the centipede, now with a dangerously electric halo around its body.
Bugmeister- in my opinion, I think that it is a greatly improved version of the mortar. It does a lot of damage and shoots bombs.
Hope this helps! LOL.
