I found this shmup when I visited Babarageo for the banner game reviewed recently on JIG. The instructions are in Japanese, but it didn't take long to figure out what to do.
Uchuwars is a classic-style shmup with weapon power-ups and bombs. Control is with the mouse for movement and left click to shoot—you can hold it down for continuous fire; the low RSI factor is nice. Bombs are used with [B] key on keyboard.
You start with 5 shield and 3 bombs on each level, and whatever weapon level you had from the previous level. In addition to weapon power and bombs, supply ships also can drop shield points (recovers one shield). Once you lose all your shield points, it's game over. Actually, you just get returned to the splash screen.
On the splash screen, clicking on the little square next to "STAGE" will cycle through the stages you've been to, and you can retry those stages with the weapon power you had upon entering those stages. If you're up for extra challenge, after you've chosen a stage you can click the square next to "POWER" to lessen your firepower.. :)
The only downside I found so far is that bombs are not very effective, and you can have, at most, 3 of them.
Overall, I thought it was a nice casual shmup with nice execution and a good look-and-feel.
A very kind cheers! to Alan for submitting this review for Uchuwars!
