Short term fun

Ive got to say this game is really fun. Harkening back to Gradius. However after only 3 hours (a few days) of gameplay Id maxed out my levels and could grow no further that way without purchasing, with actual cash, several items several times over. Why not just put a single price tag on the game? So if youre looking for a handful of hours of fun this is for you. Suppose you could keep replaying the same 12 levels and earning gold/upgrading... I love this game but would prefer to just buy it one time. Not keep purchasing ability to increase levels.
