Let SUSE's coin to appear at stage 16

2026-04-05T20:36:01Z

We want every shuttle kind to appear at least once before rewarding the player with the coin. Signed-off-by: Miquel Sabaté Solà

Add a table with tile IDs for shuttle parts

2026-04-03T20:32:52Z

This will allow us to select the proper shuttle depending on 'Globals::zp_shuttle_kind'. Hence, now only the actual shuttle parts on the CHR file are missing, which is why I left a couple of TODOs on the table itself. Signed-off-by: Miquel Sabaté Solà

Fix wrong initialization on shuttle reassemble

2026-04-02T05:51:13Z

The shuttle should be reassembled every 4 stages, not 8. I did not remember well how this worked and I jumped ahead with the conveniency of the 'Globals::zp_level_kind' variable. Signed-off-by: Miquel Sabaté Solà

Fix overwrite issues when adding scores

2026-03-27T23:27:09Z

The add_to_player() function relied on parameters to be passed on the 'Globals::zp_tmpX' variables, but that's just plain stupid. First, because these memory addresses are not meant for arguments; but most importantly, because callers actually needed some of these values before calling this function. Hence, everything went into chaos and sprites began to act wrongly in all sorts of random ways. Moreover, some of the callers also needed a guarantee on either the 'x' or the 'y' registers. Since this wasn't always feasible, we needed to store/load these registers' values case by case. All in all, now add_to_player() accepts only one argument via the 'y' register (which callers already knew it was going to be messed with). The value on 'y' has to be set via some helper constants. As a cherry on top, this not only fixes a nasty bug, but it also makes things more performant and with less code. Fixes: 63ef73de3bdd ("Update scores on screen") Signed-off-by: Miquel Sabaté Solà

Decrease a bit the items' timer

While playtesting I found the given timer's value a bit too much. Signed-off-by: Miquel Sabaté Solà

Implement the "take off" animation

2026-03-23T22:59:26Z

This is the animation that is done after clearing a stage. Moreover, and for the first time since I started development, now we can move into the next level as intended from the game's design. Signed-off-by: Miquel Sabaté Solà
