An authentic remake of a tower climbing game featuring a strange green creature.
The original was called Nebulus and also Tower Toppler and also Castelian. This version frequently refers to itself as Tower or Tower Toppler, however the in-game title screen calls it Nebulus, so that’s what we will, too.
Now that we’ve got that out of the way, exactly what is this game? It’s a tower climbing game where you scale the outside of… a tower. The tower is treacherous and contains many pitfalls, including the dreaded disappearing block. Along with you are various enemies, balls, robots, etc. who attempt to block your path up the tower. Shooting them often disables them temporarily or kills them completely. Shooting is done with the space bar, which is the same button for jumping, if you’re pressing a directional button – so try not to shoot and run at the same time.
Between levels is a simple, but fun, mini-game which is included solely for the purpose of gathering points. Shoot the fish with a rocket, then collect the fish (which is now inside a bubble). The mini-game has so little to do with the rest of the game its almost laughable – however it does provide impetus to finish levels. It’s so simple and basic it’s hard not to get hooked on it.
Included in this remake is everybody’s favourite – a level editor! This is very, very comprehensive and you might want to print out or write down all the different keystrokes involved in that process. There are enough levels presenting a lot of challenge to keep you going before you’ll need to make your own though, so happy gaming.
