Space Toads Mayhem is an arcade-style, topdown shooter paying homage to classics from the 1980s - some say it tastes like arcade-flavoured ice cream with laser blast sprinkles :) It's a challenging, reflex-based game, rewarding a player who enjoys fast-paced action and can utilise enemy behaviour to his / her advantage.
Every 20000 points you get a randomised drop, just like the space spikes power-up on the video here, causing massive damage :)
On top of that, there will be a kind of a levelling up system implemented (based on score). Each level will take longer to achieve, and every time you level up you will get a temporary power boost - but also the game will become incrementally more difficult with each level :) So for example, a good power-up drop might eventually become rare as the game difficulty increases.
