Terra Noctis is a charming 2D platformer with tight controls and level design that encourages exploration.
The game features a lot of different game mechanics: shooting, power-ups, puzzles, three different types of currency, and a bat named Columbus who guides Allen to secret areas and sometimes lets him ride around on his back.
There are different collectible items that can be spent to buy stuff. Because these items are hidden throughout each non-linear level, players are ostensibly motivated to explore. This, in turn, introduces a risk-reward element to the game.
All in all this is a very fun to play platformer, which is always welcome nowadays that almost no games of this kind are released anymore.
