I'm now curious about sploder. :O
Anyway, it was kind of lackluster so far. As Ayutac stated, you run through 3 levels with no enemies, and the powerups that are there are very pointless as a result. It's okay to add a few enemies in the levels, because it would give it more of a challenge.
I actually tried this game with the locks on. The door with the password was really frustrating because I found no hints as to what the password was in the previous levels, and you can only backtrack so much..
